But Dinesh I think ISP allocate Dynamic IP by using subnetting or distribute IP from a pool of IP.So in this case whenever a user connect to internet he get new IP from ISP and i think its not possible to maintain the record of that or trace of it. only they can trace the state or region at the time of allocation not who are using it..

PLease correct if i am wrong

Hi,

Its mandatory for the ISP to record all IP leases. they always link to to a customer ID by phone number in case of a broadband, SIM number in case of a datacard and username in case of a wireless/wimax.

hi,

of the 3 data cards i've used... It works like a VPN and gets you a ip lets say in 10.10.10.5 that has gateway of 10.10.10.1 -> that gets to a gateway of 122.x.x.153 -> so when you chk myipaddress.com from your datacard -you will get 122.x.x.153. This is how it used to be.. havnt used one for the last 6 months.

You can also connect on your datacard and do a tracert somedomain.com and see the traffic traversal...
