If you see an IP that resembles 192.168.n.n then this is an internal IP address assigned by a router. So your router is getting your external IP address. If the IP displayed in the command prompt window matches the one shown on WhatIsMyIP.com then your computer is being assigned your external IP.
ive done this and mine matches the one shown on WhatIsMyIP.com, then i tried doing this..
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
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 188.8.131.52
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. Go to https://www.whatismyip.com/ to see if you have a new IP address
but mines not changing at all, so i rang my ISP whos NTL/Chorus they told me they could not change the IP address because its dynamic.
i have also tried unplugging it all i even removed the wire from the box on the wall not sure what its called.. im not really a technology type of person, if anyone helps can you please dumb it down for me lol
Since the IP is DHCP, you'll have to do one of 2 things. Wait for the lease to expire (which is controlled by the ISP) or try a different NIC (Network Card) since the IP is being registerd to the MAC on your current NIC.
If you don't know how to replace the NIC, an alternative would be to get a router and let the router get your external IP address. The router will also have a different MAC than your current NIC.
