Your router provides the IP address to all of the devices connected to it - unless you have specifically set up static addressing. So if you ipconfig release/renew etc all that you are doing is releasing and renewing from the router and since the IP address you have just released is available for reuse, you'll likely get the same one again.

My Linksys, out of the box, is set to allocate addresses in the range 192.168.1.100 to 192.168.1.149 (a 50 address range). Yours may well be the same and so the address you see for the PC after the ipconfig should be in that range.

VM provides an IP address for the cable connection - and if you plug your PC into the cable modem then that is the IP address that your PC will get. Once you plug in your router, it takes that IP address and hides the IP addresses that it gives to your connected kit from the outside world.

How to change your public IP address? All that I have seen are suggestions to power off the modem for some period of time in the hope that during that time your original IP address gets re-allocated - so when you power up you get a new one. That's on the old Telewest side - it may be on the NTL side you can request one via the ipconfig route - if so the router has a facility to DHCP release and DHCP renew in the "Status" "Router" screen.

Hope this helps.
