hello all. first post here. great site btw. i have been reading a lot about changing ip's with long leases, and spoofing the mac address on my cable modem to change the ip. my question is: can i simply place a router(dont have one presently connecte) in line with the modem to change the ip address. if i understand correctly, the modem registers the first component it is attached to. if this is the case, the way im understanding it is, connecting a router will automatically get me a new ip. can anyone comment on this? thanks a lot.
