What's My IP Address Lookup
An IP Address (Internet Protocol Address) is an unique online identifier assigned to your computer when you connect to the world wide web through your ISP (Internet Service Provider; Comcast, SBC Global, AT&T, AOL, etc.), or your office LAN (Local Area Network) connection. Your IP Address identifies your computer from the millions of other computers on the internet. It's kind of like a fingerprint to your online identity.You can have either a Static IP Address which never changes, or Dynamic IP Address, which will change every time you login or are assigned a new address for that session from your ISP's DHCP server.
You will have to check with your internet service provider or network administrator to find out if your computer uses a static or dynamic IP address. You can also check back here every day to see how your IP address has changed or if it stays the same. I have a dyanmic IP yet it has remianed static for a long time. If you wish to change your IP Address try restarting your Modem and router.
How Do I Find My IP Address?
You can use the Command Prompt and follow the instructions below. If you use a router or firewall such as Linksys, Beklin, D-Link or Netgear to connect to the Internet then the IP address shown from the DOS Commands will not be your public IP address, instead it will be your internal private local network IP address. Internal IP address usually start with 192.168.
