BSNL claims to provide its users with dynamic ips .. so this means that the ip changes dynamically every time the user connects right ? does this mean that.. if in case he does some mischief or illegal stuff online you cant track him back since his ip has changed... so is it a boon ?

i use my dynamic ip for downloading from rapidshare !! just switch off your modem and switch back on... and you can download the next file !!
