How can I Configure my PC to obtain an Ipv6 Adressess and what are the benifts of IPv6 ?

Is your internet provider providing you with an IPv6 address? If not, you can setup IPv6 internally, but will convert over to a public IPv4 address on the way out. In any case, your network equipment must support IPv6 as well.

The main benefit of IPv6 is that its a 128bit address scheme. Plenty of IPs for everyone. No need to run NAT services at the firewall. Built in security, etc... plenty of online guides that go into the details of IPv6.
