There are people who do stuff like blah::53 for DNS, or =
blah:193:77:81:20 for a machine that has IPv4 address 193.177.81.20.
For the DNS, I always recommend using a separate /64 for each one, as =
that way you can move them to another location without having to =
renumber, and make the addresses short, so a ::1 address or something, =
because those are the IPv6 addresses that you end up typing a lot.
For all the other stuff, just use stateless autoconfig or start from ::1 =
when configuring things manually although there is also a little value =
in putting some of the IPv4 address in there. Note that =
2001:db8::10.0.0.1 is a valid IPv6 address. Unfortunately when you see =
it copied back to you it shows up as 2001:db8::a00:1 which is less =
helpful.

No, the same Internet Protocol.

Stateless autoconfig for hosts, EUI-64 addressing for routers, VLAN ID =
in the subnet bits. That makes life simple. Simple be good.
