DNS Setup
As with IPv4, without DNS, the Internet isn't very useful. Unlike IPv4, IPv6 addresses are much, much, larger. Typing addresses for a given site is both tedious and painful. You need V6 DNS.
Setting Up DNS
If one is already running BIND on the router, the setup for V6 is trival. Look in the named.conf file. Look for the line
listen-on port 53 { any; };
Add the line
listen-on-v6 port 53 { any; };
This line simply tells the DNS server to listen on V6 as well as V4.
