OK, what am I missing?
I'm not as versed in DNS protocols as I was in the past (which then
didn't compare to some on this list), but won't this cause tons of "lame
server" messages that could be eliminated by proper SWIPping?
The holder of the /16 _has_ delegated rDNS for the 32 /24s to the /19 owner.
The /19 owner can, on it's nameserver, run an "authoritative" zone for
the /16 -- with _its_ /24s listed explicitly, and a wildcard pointing
back to the rDNS nameserver of the /16 owner.
"He who" queries from the outside world will work their way down from the
.arpa zone, to the X.W.in-addr.arpa zone, get referred to the nameserver
at "thiscompany", and get referred to the NS listed for Y.X.W.in-addr.arpa.
which will resolve Z.Y.X.W.in-addr.arpa.
