Details about your IP address:

This is the IP address of the machine that requested the page. Typically this is your own IP address. If you used a router/proxy you will not get the correct IP address. If you use a home router to connect to the Internet (or your company has a proxy), the IP address shown will be address of your router or proxy. If you use a router and you want to run a server on your computer, you may need to place your computer in the DMZ settings of your router, or enable port forwarding on your router. If you have a network connection that gets a dynamic IP address and you want to give it a domain name so people can reach it easier, you might be interested in Dynamic DNS.

If you would like to look up a domain name and get information about the host, you may look it up by doing a whois search.

To see if your IP address has a Domain Name associated with it, you can do a reverse lookup.

A little bit about your IP address (Internet Protocol address). When you connect to the internet, either via your internet service provider (Verizon, Cable Vision, etc.), or your office LAN connection, you are assigned an IP address. This address identifies your computer from the other computers on the internet. Your IP address can be either static, meaning it never changes, or dynamic, meaning each time you connect online you are assigned a new address for that session. Check with your internet service provider or network administrator to find out if your computer uses static or dynamic IP addressing.

The commands below will show you the IP address of your computer. If you use a home router to connect to the Internet, the IP shown from these commands will not be your public IP address (it will be your internal IP address). Internal usually IP address start with a 10.10 or 192.168.
