Reverse DNS question

[W_Prindl]

So there seems to be your problem on the DHCP-side of your
configuration. You have an 1.16.172.in-addr.arpa zone - but you need a
16.172.in-addr.arpa zone.

These zone definitions in the DHCP config are just a necessity of the
use of the dhcpd daemon on OES Linux and are needed to tell the dhcpd
daemon, where he should send his DDNS updates. (Of course it would be a
nice feature, if these entries were created automatically for all zone
definitions, which are existing in the DNS configuration, but Novell
has decided, that you have to do that manually.) They should be the
exact copy of the corresponding zones in the DNS configuration.

Before you delete the 1.16.172.in-addr.arpa zone look at the IP-address
of the DNS server listed there, maybe that does belong to another DNS
server and that is the reason you do not see any resource records for
this zone but RDNS queries for this zone do work.
