This post also highlights a major thing I discovered when deploying and using IPv6, which is that you don't "Lift and shift" IPv4 to IPv6.
This is one of the reason its hard to deploy, because people cannot use the same IPv4 concepts to IPv6. For unknown reason they do, they will find the same problem they had with v4.
Which some also do not sort nicely. Specially when combined.
0177.1 (octal, 2 stripped 0s, decimal one)
017700000001 (octal)
2130706433 (decimal)
127.0.0x1
0x7f.0x0.0x0.0x1
127.000.000.001"sorting by ip" for example is eschewed in favor of router advertisements where hosts pick their own subnet delegations.
one of the ways you track all of this is using a dhcp6 server with dns updates turned on. the subnet delegation is picked up by the client, which in turn pings dhcp6 and reports its IP for update in the DNS server.
If only it were that easy.
