I just wanted to know if i am using dynamic ip am i unable to use
proxy any more or there is a way to use a proxy of anoher country

There is no such thing that Dynamic ip's cant use proxies.you have to
just set address of the proxy server and its port in the browser you
are using.

To check whether Your ip is Dynamic issue the command ipconfig /all
for WinX machines.if there is a DHCP entry saying yes.Then u have
Dynamic IP's.

This obviously doesn't apply in all cases, just done this on my ADSL
connection and although I know I don't get issued a static IP the DHCP
enabled field reads 'no'.

Can you please explain exactly what you're trying to do.
