HOW TO CHANGE IP ADDRESS?

i have tried several things that havent work

ipconfig/release

ipconfig/renew



i have done ipconfig/release then went to Internet Protocal changed the ip. then search for Ip automatically after changing it and that didnt work. My ip doesnt change every time i connect so im assuming its static.

i tried unplugging everything from modem for 3 hours and that didnt work.

im planning on turning it off over night (8-10) hours does any1 have a different method?

HOW TO CHANGE IP ADDRESS?
By changing internet service provider or changing the computer you use.
