Is having an IPv6 reverse lookup zone necessary for an Active Directory network?
Normally I would just create it and move on, however, in this case the prefix is delegated and changes occasionally. So I have to create a new one every time the prefix changes.
fc00::/7
range (fd00::/8
), and the next 40 bits must be randomly assigned. The leaves you 16 bits for subnetting (65,536 subnets) before you need to get another 40 random bits. – Ron Maupin Mar 9 '17 at 6:25
