Spoofing my IP
sometimes poorly configured isps will let you use any of there ips, but if its already in use then the person you tried to take it from would notice something was up right away. if the purpose is to be anonymous then do it from some free wifi place, and while you're on the network dont do anything that would link it back to you ie sign on myspace. then never connect to that network again.
Mac address is for local network, not Internet … … …
Not true, I believe. Java uses MAC addresses too, I've seen websites blocking certain IP/MAC combo's this way, gotta hate them applets.
Anyway, spoofing IPs. Trust me, you won't be able to do it. It takes A LOT of time, A LOT of skill and probably a private DNS server too ;x. You just need to use a proxy to hide your ip, easier, trust me.
