i am connected to nett trough netcomm router.
when i do ipconfig i get my ip address as 192.xxx.x.x.
Its probably an 192.168.0.0/16 address. These addresses are defined in RFC-1918 and are so called "private" IP ranges.

question is:
what is my "proper "ip adress.
when i visit some sites it says my ip address is 220.345.xxx .x
That is your "proper" Internet address.
Why is that?
Your router is using Network Address Translation (NAT). It "translates" all traffic going to the Internet to your "proper" Internet address.
