I was pleased that I was able to get our two (successive) ISPs to set up reverse DNS for our small number of IP addresses, and each twice to change them when they moved us to moved us to new IP ranges (due to the IPv4 crunch). It never even occurred to me that it might be possible to have them delegated to our DNS server (which could handle it, being BIND running native on a Linux VM on their hardware -- no "helpful" ISP mandated interface software to interfere with configuration).
P.S. Unfortunately our 2 current IPs, although adjacent, are not /31, and thus would require 2 delegations On Fri, 27 Dec 2019 13:40:11 -0700 Grant Taylor via bind-users <bind-users@lists.isc.org> wrote: > On 12/27/19 1:22 PM, Reindl Harald wrote: > > nobody out there will delegate single /255 ip's > > I've had multiple different ISP's delegate reverse DNS for single IPs > (/32 or /128) multiple times. > > Some used RFC 2317 Classless IN-ADDR.ARPA Delegation, others used > standard delegation. > > Some ~> many ~> maybe most will not delegate in any way.
