I read through the whole thread but I don't think I grasped what OP is trying to do here. Which one of these two are you attempting to do?

1. Are you trying to change the IP address of your internal network card (one that is physically attached to your computer)?
2. Are you trying to change the WAN IP address that your modem is using from your ISP to connect to the internet?

About changing the modem-IP:
    A legal way to change the IP of your modem would be to simply reboot it. But this only works if
    you have a modem with dynamic IP. As you already tried it,and it didn't work,it seems your
    modem isn't supporting dynamic IPs. (To get more detailed info just type the modem IP in
    your browser and press enter.)
   
    The second way would be to crack your modem and change the IP this way.

And don't forget:
    If you load a page for example,the modem requests the data-packs from the server. If you
    change the IP while the modem still loads the data from the server,the server won't know
    you changed IP and will still send the data to the (now not anymore existing) IP and not to
    your new modem IP,so you won't recieve any data anymore,till you request the data again.

Well I guess since whatsmyip tells me my IP is the same no matter what I do(mac change, trying to assign myself a new IP, ipconfig release, blah blah) then I guess I'm asking about changing the WAN IP


@Area 13- My router does support dynamic IP's so I could just turn off my modem/router/everything and turn it back on and I'd have a new IP?

Since your trying to change the WAN IP, you will need to contact your ISP. They are they only ones who can do it without proxy routing.


I worked tech support for a DSL company, and we could change IP's, only if it was DHCP or PPPoE. They do can release/renew from their end called clearing the IP. Another procedure they can do is called a kill/build which kills the circuit between them and you, then rebuild on a different server.


If you where trying to change your LAN IP, then in windows, you can change the IPv4 TCP settings to use a static address instead of the DHCP. You will need to enter a valid IP, with a valid netmask which is usually a class C configuration.


You can also release and renew in the router/modem itself by logging into the web gui.


But as for the external address, your ISP will have to do it.

I had a feeling. It was more of an inquiry than something I was really striving to do I just wanted to know if I could. Thanks

EDIT: I found out my IP lease expired yesterday. Shouldn't that mean that today I should have a new WAN IP? Or is that just for the internal IP

If you have a modem with dynamic IP,rebooting it should be as far as I know enough to change the modem IP. 'cause everytime I reboot my modem (wich is also supporting dynamic IP) i get a new IP by my ISP

If you found the lease time doing something like ipconfig then it's your internal ip.


And when the lease expires it doesn't mean 100% you'll get a new IP, because the network stack is pulling IP's from a DHCP pool. You could end up with the same IP every time.
