[rpd] Lame Delegations in AFRINIC Reverse DNS Proposal

Some background - I've been involved with the CO.ZA registration system
for about 23 years. Our policy was to only allow a new delegation into
the zones once the nameservers were all authoritative - i.e. Don't add
broken stuff.

I'm now looking after another smaller zone and although I still follow
the manta of not adding broken stuff, I'm finding that there are lame
Delegations so I will be adding automated periodic checks and informing
people when there are problems.

I also agree with this - perhaps between two and four times a year.

For ARIN to do this is difficult, as ARIN has inherited a lot of Legacy
users - often without correct contact information. This is not the case

No, its more than that. One point not brought up and emphasised is that
the owners will be contacted in this process - allowing them to fix things.

More often!

I'm sure the algorithm would be something like that.
Check. if broken - re-check after 2 days, then four days, then eight
days then mark as bad. (Like how mail delivery works)
