Daftar nama port yang sering digunakan

Dalam protokol jaringan TCP/IP, sebuah port adalah mekanisme yang mengizinkan sebuah komputer untuk mendukung beberapa sesi koneksi dengan komputer lainnya dan program di dalam jaringan. Port dapat mengidentifikasikan aplikasi dan layanan yang menggunakan koneksi di dalam jaringan TCP/IP. Sehingga, port juga mengidentifikasikan sebuah proses tertentu di mana sebuah server dapat memberikan sebuah layanan kepada klien atau bagaimana sebuah klien dapat mengakses sebuah layanan yang ada dalam server. Port dapat dikenali dengan angka 16-bit (dua byte) yang disebut dengan Port Number dan diklasifikasikan dengan jenis protokol transport apa yang digunakan, ke dalam Port TCP dan Port UDP. Karena memiliki angka 16-bit, maka total maksimum jumlah port untuk setiap protokol transport yang digunakan adalah 65536 buah.

Berikut ini daftar port yang sering digunakan

PORT	TCP	UDP	KETERANGAN
7	TCP	UDP	Echo protocol ( protokol untuk ping )
15	TCP	UDP	Netstat service ( melihat aktivitas jaringan )
20	TCP		FTP (File Transfer Protocol, Default data)
21	TCP		FTP (File Transfer Protocol, control, connection dialog)
22	TCP		SSH (Sistem secure shell), SCP (SSH untuk copy)
23	TCP		Telnet
25	TCP		SMTP (outgoing email)
43	TCP		Whois protocol ( command untuk melihat informasi host dalam jaringan )
53	TCP	UDP	Domain name server (DNS)
67		UDP	Dinamic Host Connection Protocol ( DHCP )
80	TCP	UDP	HTTP
110	TCP	UDP	Pop 3 (incoming email)
137	TCP	UDP	Netbios name service
138	TCP	UDP	Netbios Datagram service
139	TCP	UDP	Netbios Session service
220	TCP	UDP	Internet message Access protocol ( IMAP ) vertion 3
389	TCP	UDP	Lighweight Directory Access Protocol ( merupakan DHCP di Linux )
443	TCP		HTTPS ( versi HTTP yang secure / aman )
513	TCP		Remote login ( melakukan login remote desktop )
520		UDP	Routing information protocol ( untuk melihat routing jaringan )
1194	TCP	UDP	openVPN ( virtual private network ) untuk konek ke komputer di luar jaringan
5900	TCP	UDP	Virtual network computing ( VNC ) , remote komputer
8080	TCP		HTTP web proxy
10000	TCP		Webmin Linux

Demikian sebagian dari daftar port yang sering kita gunakan, masih banyak port-port yang mungkin belum kita ketahui, untuk lebih lengkapnya klik disini

IP WHOIS LOOKUP !!!

IP Address Lookup

The IP Address Lookup tool often referred to as IP Lookup, Lookup IP, Lookup IP Address, IP Address Location, IP Location, and IP Locator is designed to give you an idea of where your IP Address or the IP Address you lookup is located. This tool is not 100% accurate due to many different factors. Some of those factors include where the owner of the IP has it registered, where the agency that controls the IP is located, proxies, cellular IPs, etc. If you are in the US and the controlling agency of the IP is located in Canada, chances are your IP location will show as Canada. Showing a Canadian IP while in the US is very common among Blackberry users on the Verizon network.

The results of this IP Address Lookup utility include the IP Address, Host Name, City, Region / State, Postal / Zip Code, Country Name, Country Code, Time Zone, Latitude, Longitude, ISP, Domain Name, Net Speed, and IP Decimal.

Often, people think if they lookup an IP address, that they are going to find the physical postal address of the user assigned the IP in question. This is simply not true. At this time, we are not aware of any IP address database that will give you the exact physical postal address of the IP address you lookup. At best, you'll get the exact city in which the user of the IP is located. For an exact physical address you would need to contact the ISP (Internet Service Provider) of the IP address in question. However, without a police warrant, or some sort of legal document forcing the ISP to turn over the information, don't expect them to give you the physical postal address of the user that was assigned the IP at the time you received the offensive email, or other means of offensive / questionable communication from said IP. The best you can do in this case is to file a complaint with the ISP and forward them all of the information from the offensive / questionable communication regarding the complaint. If you have any questions about the IP Address Lookup tool or the results, please check out our IP Address Lookup Forum.

For a more thorough definition of IP Address Lookup, please refer to the definition article at Wikipedia.

What Is MAC Cloning ?

MAC cloning can only be done at your router providing it has those capabilities. Most ISPs assign their IPs based on the MAC address in your equipment. If the MAC address of your router is 00-11-22-33-44-55 and you connect to your ISP, the DHCP server records your MAC and assigns an IP. If you disconnect from the ISP, you lose your IP address. The next time you connect, the DHCP server sees your MAC, looks to see if it has assigned an IP address to you before. If it has and the lease time has not expired, it will most likely give you the same IP address you had before disconnecting. Why clone a MAC address? New MAC address most likely equals new IP. How to clone your MAC and if your router has this feature is dependent on the router itself. You’ll need to find the instructions on the manufacturer’s website. Check out our Router Support page to get started.

What is a MAC Address ?

A MAC address is a physical hardware address assigned to each device that has the capability of connecting to a network. The internet is nothing more than a large network. The MAC address is something that is assigned in the chip on the device and is not something the user can change.

What is IP Address Management ?

What is IP Address Management or IPAM?

By breaking down and assigning your internal IP block into segments allows faster troubleshooting when monitoring the network and seeing an erratic IP. Because you’ve segmented the IPs out, you’ll know exactly which segment it’s coming from and can narrow down finding it faster.

Why manage IPs?

Easily track when network monitor software shows errors. If you’re logged on locally to a User’s computer and you’re mapping batch file didn’t run and you need to get a file from one of your servers you don’t have to know the server name, you can simply type \\192.168.1.x to get access to the server you’re needing the file from.
In the scenario I explain below, we’ll have 1 External IP, 5 servers ((Static) 1 handles DHCP (2k3)), 10 printers (Static), 200 wired PCs/users (DHCP).

There are several different ways to set up exact scenarios. This scenario will explain IP Address Management (IPAM) for a small network using my experience and knowledge.

For ease of use, we’re going to say that this is in a brand new facility where no IPs have been assigned and you, as the LAN Admin, have just been told your internet connection is in place and ready to use (this is where the single external IP comes from).

You already know how many devices will be connected to your network in the beginning so it’s now time to lay out a plan. Since most everyone is familiar with the 192.168.1.x IPs, I’ll stick with those. Technically, your first IP is 192.168.1.0 and your last is 192.168.1.255 which gives you 256 IPs. I don’t know of anyone that uses 192.168.1.0. Since we’re human, the first number to us is 1. To a computer, the first number is 0. I don’t think .255 is useable so really, you have 254 IPs available. Your 5 servers should get your first 5 IP addresses and assign them statically even though you can control static assignment in DHCP. You don’t want there to be any chance of these servers losing their IP addresses so you don’t want them to depend on DHCP for IP assignment.

Server 1 also happens to be your DHCP server: 192.168.1.1
Server 2: 192.168.1.2
Server 3: 192.168.1.3
Server 4: 192.168.1.4
Server 5: 192.168.1.5

You have to account for growth so leave .6 through .9 open for future servers whether they’re physical or virtual, they’ll need an IP.

You have 10 printers that will be used by multiple users. IPs in the next segment of the block can be statically assigned at the printer or via the DHCP server…your choice. Every office has a “main” printer/copier/fax. Give it 192.168.1.10. If you think far enough in advance and know that Group 1 will use printer 1 then assign printer 1 192.168.10.11, printer 2 for Group 2 would get 192.168.10.12, etc. all the way through .19. In my experience, if there’s any one piece of equipment you’ll add to your network more than any other, it’ll be a printer. Somebody in one of those groups will get tired of walking 15 feet to the printer and suck up to the boss to get their own printer. Then, people within 5 feet of that person will want to share with them so they don’t have to walk 15 feet to get their stuff either. So that printer will need to be on the network vs. just connected directly to the complainers PC and shared. Lucky you. By the way, remember at the beginning I said this was a brand new facility….hopefully, the people that ran the network drops put in 2 cables at each requested location. Otherwise, you’ll either need to run a cable or take the easy way out and install a 5 port switch. Trust me when I say leave plenty of IPs open for future printers. I would assign .10 through .29 for printers. This gives you 20 IPs for printers so you’ll have 10 IPs free after installing the initial 10 printers.

Finally, we have 200 PCs that will all be hardwired to the LAN and will each need an IP. Starting at .30 going through and including .254 gives you 225 IPs. I’d start my scope in DHCP at .40 through .254. That gives you 215 IPs for users (15 extra) and that also leaves 10 IPs open at the lower range (.30 through .39) for device growth. One thing I didn’t mention yet was managed switches. They’ll need IPs. You can do those at the high end of the spectrum so they’re “out of the way”. Maybe assign them .254, .253, .252, etc. depending on how many you have.

IPAM can get pretty deep especially if you’re dealing with 100’s of PCs and devices. This is where subnetting comes in. I’ll go into further detail in another article, but just for gee whiz this is the tip of the iceberg on subnetting:

For example, 192.168.1.1 with a subnet of 255.255.255.0 is not on the same network as 192.168.2.1 with a subnet of 255.255.255.0 even though they both might be in the same building. However, if you change the third octet in the subnet to 0 like this 255.255.0.0 now 192.168.1.1 with a subnet of 255.255.0.0 and 192.168.2.1 with a subnet of 255.255.0.0 are on the same network. The 255 is sort of a true/false in simple terms, but can get pretty complex if you’re trying to keep networks separate. I’m not a subnet guru by any means, but if you Google subnet calculator you can get a pretty good appreciation for its complexity.

How To Change Your IP Address ?

How do I change my IP? There are MANY methods to change your IP. Some methods will work for you but may not work for someone else and vice versa. If your IP is static, then you CAN’T change it without contacting your ISP. If you have a long lease time (explained in this article) on your IP then you won’t be able to change your IP without cloning your MAC address, which I’ll explain later in this article. It definitely helps if you know how the IP is being assigned to you. You can read our DHCP definition to get a better understanding.

What is an IP lease time? IP lease time is the amount of time your ISP determines you’ll be assigned a particular IP. Some IP lease times are just a few days and other IP lease times could be set for a year or more. This setting is completely up to your ISP.

One of the easier methods to change your IP is to turn off your modem/router/computer overnight. Then turn it back on the following morning. This method WILL NOT work if your ISP has a long lease time set for your IP.

The following method will ONLY work if your computer is being assigned your external IP and not a router.

How to determine if your computer is being assigned the external IP

If your connection is direct to your computer and your computer gets the public IP and not a router, you can try this:

For Windows 2000, XP, and 2003
1. Click Start
2. Click Run
3. Type in cmd and hit ok (this opens a Command Prompt)
4. Type ipconfig /release and hit enter
5. Click Start, Control Panel, and open Network Connections
6. Find and Right click on the active Local Area Connection and choose Properties
7. Double-click on the Internet Protocol (TCP/IP)
8. Click on Use the following IP address
9. Enter a false IP like 123.123.123.123
10. Press Tab and the Subnet Mask section will populate with default numbers
11. Hit OK twice
12. Right click the active Local Area Connection again and choose Properties
13. Double-click on the Internet Protocol (TCP/IP)
14. Choose Obtain an IP address automatically
15. Hit OK twice
16. Check your IP to see if you have a new IP address

For Vista

1. Click Start
2. Click All Programs expand the Accessories menu
3. In the Accessories menu, Right Click Command Prompt and choose Run as administrator
4. Type ipconfig /release and hit enter
5. Click Start, Control Panel, and open Network and Sharing Center. Depending on your view, you may  have to click Network and Internet      before you see the Network and Sharing Center icon
6. From the Tasks menu on the left, choose Manage Network Connections
7. Find and Right click on the active Local Area Connection and choose Properties (If you’re hit with a UAC prompt, choose Continue)
8. Double-click on Internet Protocol Version 4 (TCP/IPv4)
9. Click on Use the following IP address
10. Enter a false IP like 123.123.123.123
11. Press Tab and the Subnet Mask section will populate with default numbers
12. Hit OK twice
13. Right click the active Local Area Connection again and choose Properties
14. Double-click on Internet Protocol Version 4 (TCP/IPv4)
15. Choose Obtain an IP address automatically
16. Hit OK twice
17. Check your IP to see if you have a new IP address

Some people have inquired about manually assigning their IP address. This IS possible, but you run a very high risk of your ISP banning you from connecting to the internet. To manually change your IP, follow the steps above for your Operating System. In step 9 or 10, depending on your O/S, enter an IP similar to the one displayed in the command prompt window. For example, if the IP displayed in the command prompt window is 75.1.2.3, change yours to 75.1.2.4. You’ll also need to manually enter the Subnet, Gateway and DNS Server IP addresses as well. If the new IP you give your computer doesn’t work, chances are someone else on the ISP network has already been assigned that IP. You’ll need to move on to the next one and keep trying until you find an open one. However, some ISPs match up your MAC or modem data to the IP that’s been assigned. If those 2 things don’t match up, you won’t be able to connect no matter what. If your router gets the IP and not your computer, you’ll need to http in to your routers interface and manually assign the IP there. It’s pretty much the same method as assigning the IP to your computer. The method that varies is in how you reach your routers interface. You can get the instructions from your manufacturer’s website.

MAC Cloning. What is a MAC address? A MAC address is a physical hardware address assigned to each device that has the capability of connecting to a network. The internet is nothing more than a large network. The MAC address is something that is assigned in the chip on the device and is not something the user can change.

The next time you connect, the DHCP server sees your MAC, looks to see if it has assigned an IP address to you before. If it has and the lease time has not expired, it will most likely give you the same IP address you had before disconnecting. Why clone a MAC address? New MAC address most likely equals new IP.

What Is An IP Address ?

IP Address (Internet Protocol Address):

This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network. There is a standard of communication which is called an Internet Protocol standard (IP). In laymans terms it is the same as your home address. In order for you to receive snail mail at home the sending party must have your correct mailing address (IP address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet. Without this specific address, information cannot be received. IP addresses may either be assigned permanently for an Email server/Business server or a permanent home resident or temporarily, from a pool of available addresses (first come first serve) from your Internet Service Provider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.

Domain Name System (DNS): This allows the IP address to be translated to words. It is much easier for us to remember a word than a series of numbers. The same is true for email addresses.

For example, it is much easier for you to remember a web address name such as whatismyip.com than it is to remember 192.168.1.1 or in the case of email it is much easier to remember email@somedomain.com than email@192.168.1.1

Dynamic IP Address: An IP address that is not static and could change at any time. This IP address is issued to you from a pool of IP addresses allocated by your ISP or DHCP Server. This is for a large number of customers that do not require the same IP Address all the time for a variety of reasons. Your computer will automatically get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations. This number can be assigned to anyone using a dial-up connection, Wireless and High Speed Internet connections. If you need to run your own email server or web server, it would be best to have a static IP.

Static IP Address: An IP address that is fixed and never changes. This is in contrast to a dynamic IP address which may change at any time. Most ISP's a single static IP or a block of static IP's for a few extra bucks a month.

IP version 4: Currently used by most network devices. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly. Just like in a city, addresses have to be created for new neighborhoods but, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 is limited to 4,294,967,296 addresses.

IP version 5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX (a computer Operating System) release conventions, all odd-numbered versions are considered experimental. It was never intended to be used by the general public.

IP version 6: The replacement for the aging IPv4. The estimated number of unique addresses for IPv6 is 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128.

The old and current standard of addresses was this: 192.168.100.100 the new way can be written different ways but means the same and are all valid:

* 1080:0000:0000:0000:0000:0034:0000:417A

* 1080:0:0:0:0:34:0:417A

* 1080::34:0:417A

What's The Difference Between A Static IP Address And A Dynamic IP Address?

A static IP is one that will never change. A dynamic IP is exactly that, dynamic. It could change frequently, or not change for more than 1 year. It really depends on how the DHCP server that’s assigns the IPs is set up.

What Is DHCP ?

Dynamic Host Configuration Protocol ( DHCP )

     In simple terms, DHCP determines if your IP is static or dynamic. DHCP is controlled by a DHCP server. Your router can be a DHCP server...and if you're on a home network, it most likely is your DHCP server.

     I know this might be confusing because the word dynamic is in the term, but just because you have DHCP enabled on your computer doesn't mean you can't be assigned a static IP. DHCP enabled on your computer simply means you're letting a DHCP server assign its IP. Having it enabled DOES NOT mean it's a DHCP server.

     A true DHCP server (not your Linksys router) gives the LAN Admin a ton of control with IP assigning.

Ever print to a network printer? Ever wonder how that printer keeps its network assignment? Probably through DHCP. Each network device has a MAC address. You can assign a static IP at the DHCP server to a specific MAC address. This allows the network printer to always get the same IP even after it reboots and without assigning the IP at the printer. If you print the network configuration at the printer, it will probably tell you that DHCP is enabled and no static IP is assigned. That's because the IP assignment is handled at the DHCP server.

    Your ISP has a DHCP server. They can assign IPs by modem MAC addresses. When your modem comes online, it communicates to the network indicating it is looking for an IP address. The DHCP server listens to this communication and starts talking to the modem. The modem then transmits its MAC address to the DHCP server. At that point, either an IP has been reserved for the modem or one is assigned at that time. Hence cloning your MAC address to get a new IP from your ISP.

     Routers and DHCP - Under the General Setup or LAN Setup tab in your router, you'll see a settings option for DHCP. You can control how many IPs are assigned or to enable/disable the DHCP server portion of the router. If you disable it, you'll have to statically assign IPs to each computer, or have a DHCP server or your network. This goes for wired and wireless. Any connection on your network has an IP address.

There's a lot more to DHCP than this, but this is a basic explanation.
