Hi there,
I’ve got an Setup which works well on Debian, Freebsd and OpenWRT, which adds dynamically PTR Records via DHCPd to Named. The issue they I’ve got is that instead the last octet of an IP Address all four octets of the address get submitted. This is not that what I want 
Adding regular DNS is working fine.

NS troonedier.webterrorist.lan.
$ORIGIN 228.23.172.in-addr.arpa.
$TTL 3600 ; 1 hour
52.228.23.172 PTR Mac-mini.webterrorist.lan.
But instead “52.228.23.172 PTR Mac-mini.webterrorist.lan.” it should be just “52 PTR Mac-mini.webterrorist.lan.”
and this happens on openSuSE 15.5 only. Anyone have an idea how I could fix it?
