Nice idea. Always wondered why IPv6 went so ambitious with the addressing

One of the craziest aspects of IPv6 implementation is the reverse DNS lookups.

IPv6 uses ip6.arpa and segments each little nybble into a subdomain!

https://en.wikipedia.org/wiki/Reverse_DNS_lookup#IPv6_revers...

This means there are always 32 octets to a reverse-IPv6 address, and there are no shortcuts or macros to overcome this! That means if you wish to assign a singular name that maps from a legitimate /64 Network ID, you must populate 64 bits worth of octets in a zone with this data. It is an absurd non-solution. This never should've been allowed to happen, but it will basically mean that ISPs abandon reverse DNS entirely when they migrate to IPv6 implementations.

Might as well go big. 24 extra bytes per packet is not that big deal. And having that much extra space means you can screw up design multiple times and still be able to reuse lot of infra. Also getting rid of idea that you are even trying to manually manage the address space eases many things.

		But it's not human readable anymore, nor backwards compatible. The expectation was that the industry is reasonable, but it proved to be as hard as it would be to push breaking email v2 implementation.
