To view your ip go to Start the Run and type command

at the dos prompt type ipconfig.

Depending on what ver on windows that you have type ipconfig /release_all or ipconfig /release

Then type ipconfig /renew _all or ipconfig /renew

Then type EXIT

This will release and renew your ip address but will ont mask it.

There are programs that do mask it.

But I do not advise you of getting them. Few IP will not able you to mask you ip address.

Just like to comment before, go to a public place where you have computer access with internet and place a order there.

Good luck
