reverse zone for 192.168.x.y not working but 192.168.100.x does

192.168/16 isn't a class B, it's a class C address block. Aside from
that, you've named your RRs wrong. You reverse the four octets of the
IPv4 address and append in-addr.arpa to get the node at which a PTR
record should be available, so you'd need to say (for example):

> $ORIGIN 168.192.in-addr.arpa.
> 1.100 PTR whatever.

This will cuase 192.168.100.1 to reverse-resolve to "whatever.".

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
