Which one?
"If we gave them static IPv4 addresses we will give them static IPv6 =
addresses"
Or
"SLAAC(autoconfig) vs DHCPv6"
For the first ... at the simplest, it is familiar and comfortable.
In general:
Servers, Routers, Firewalls, Switches (atleast those with L3 addresses) =
=3D=3D static address
Hosts =3D=3D dynamic ... either SLAAC or DHCPv6. Manual Configuration =
of hosts is a non-starter for most environments.
For the latter ... that gets more involved.
Many (most?) platforms do not support DHCPv6 client functionality. =
Ditto on the server side.
OTOH, SLAAC alone cannot currently give you DNS information ... a =
possible deal-breaker, that.
(Some work under way to change that, or the environment can cheat 0 rely =
on IPv4 transport for DNS :) )
