Windows Clients has a small program which autoregisters any IPv6 address to
the hostname as soon as they appear. Windows Servers are configured to avoid
privacy extensions and stick the the "per installation" IP address.
Linux/Unix systems as well as routers are manually configured to use a
static IP addresses (usually derived from the IPv4 address).
Autoconfig is always on to prevent rouge autoconfigs from guest or
uncontrolled (after each patch day) systems. We do not use DHCPv6 but serve
the well known (depreceated) site local anycasts.
Periodically polling the ipv6 neighbor table of the LAN routers and
dynamically generate (auto timed out) rDNS entries "non-EUI64-rnds CNAME
EUI64-rnds" using the MAC address from the neighbor table finishes the setup.
