So how can you change your IP address. I have TW cable internet so not sure if I have to contact them to do it.

Unless you pay extra for a static IP, the IP that is provided to your modem is dynamic (e.g. it is allocated to you from a pool and will eventually change).

if u have a router, change its MAC, the modem will give it a new ip after u reboot it..

Or not. I've had the same one for years. It depends on how your provider's DHCP is configured.

Unless you have a static ip address, just unplug your modem for like 30 seconds and you should get a new one when it reconnects.

Or

If your computer is hooked straight to the modem and not through a router, go to start, run, type cmd, then in the window type ipconfig /release, then ipconfig /renew that will also give you a new one.

If you change your MAC you will probably have to let the cable company know about it. Otherwise, your Interweb may stop working.

Good point. If the DCHP lease is set to a very large expiration time, you basically get a static IP for free.

I've had the same dynamic IP address for years. I haven't tried an IPCONFIG/RELEASE followed by an /RENEW to see what happens with my ISPs DNS.



+1 on release and renew to try


normally though if you leave the cable modem off overnight. replug it back in and you might get a new ip address

Alot of factors depends on your cable company and their systems. Some pable companies use your cable modem's HFC mac address to permit access and get DHCP leases by. You can't change the HFC mac. Some companies use the HFC mac to grant access and the computer mac to grant DCHP leases. In this case, changing your computer network card or router mac may effectivly give you a new IP. Other companies use your computer/router mac to grant access and lease IPs to. In this case changing your mac will deny you access to the network.

Some cable companies grant long lease times while others are short. you may be able to call your cable company and ask them to delete your lease to change your ip address.
