Obtain New IP on Static Network

Next time you're talking to a Cable Tech Representative, don't let them tell you that you cannot change your IP at will at any time. It's quite simple and doesn't require anything fancy at all. All you need is to be running Windows, and knowledge in Command Prompt. I'm not going to bore you with the basics behind how your your cable company slaps a static IP address on you, instead I'll get right to the point.

Windows XP

Firstly, hold down the Windows flag button, and press R.

Type CMD to open Command Prompt.

Type ipconfig and jot down your IP address.

Type ipconfig /release.

Now reach behind your cable modem with a pen handy, and trigger the modem's reset button.

Wait for it to cycle completely on, then wait for your computer to tell you your connected to the network again.

In command prompt, tyle ipconfig /renew.

Type ipconfig again to make sure you're on a new IP address. :)

Windows Vista

Same steps as above, but instead of typing cmd in Run, go to Start, All Programs, Accessories, Right click Command Prompt, and choose Run as Administrator.

Now enjoy having a new IP address on your "Static" network.

Hm... Seems like you got static and dynamic mixed up a bit, haven't you?

I don't think so, unless I'm mistaken on the way the network works..

Static means that the network's IP address doesn't change at all.

Dynamic means that the IP address on the network changes randomly, on it's own, at different times.

You're essentially right. Static, in this case, refers to IP retention or persistance since a lot of cable networks don't change the IP very often.

In XP, there was a DCHP IP FORCER program that would do this automatically. Since changing to Vista, it's not as automatic but still relatively easy.

ipconfig /release
power-off modem for 10+ seconds
power-on modem
wait for modem to reset
ipconfig /renew

(I have to use ipconfig /renew twice sometimes)

So it's still easy, you just need to have easy physical access to your modem and you're good to go!
