Once upon a time, Forrest Christian (List Account) <lists () packetflux com> said:I have a feeling that I might be stepping into a can of worms by asking this, but.. What's the current thinking around reverse DNS on IPs used by typical residential/ small business customers.I don't see any benefit to programmatically-generated reverse DNS. I stopped setting it up a long time ago now. Really, reverse DNS these days is mostly only useful for: - mail servers (where it shows a modicum of control and clue) - infrastructure/router IPs (so mtr/traceroute can show useful info)
I view complete DNS coverage to be a basic function. All used addresses should have forward and matching reverse records. This is not difficult stuff. Bonus points for including a clli code or similar indicating the general location of use for uses like network device interfaces, commodity end-users, etc; also not difficult stuff. You are tracking your allocations, right? Programmatically generating your device configurations? So, generate DNS from that same database(s).
