When hosts self-configure their low 64 bits, do you install a suitable PTR and AAAA into your DNS? If so, how? Do you use DHCPv6 and have it install the DNS? Do you do something else?
If you care, you probably need to use DHCPv6 for this and it should be able to build both the AAAA and PTR records.
Unless you use, privacy extensions, the advantage of IPv6 over IPv4 is that the IP address is built based on your network and the mac address of the interface, so it is not a random number changed at every connection.... I guess when you provision the machine, you can install the AAAA and PTR record and then also put the mac address in your access lists...
