[ some snipping ]


GW> I never heard of a subnet starting with 250

And, chances are it doesn't; only a /31 (!) can start on ...250,
and those are used _only_ for routing links.  But one needn't do
DNS for an entire subnet.  RFC2317 for more info.

Note that I did a bit of "dig"ging, and the delegation looks...
well, a bit weird.  It appears that more has been delegated, and
254 has not.  Multiple CNAMEs are a bad thing.


GW> You must have something like 248 - 255  (/29 net) or 252 - 255 (/30 net)
GW> For instance on the 248
GW> 248 is the network
GW> 249 is most limely the gatewaay
GW> 250 - 254 are for your use
GW> 255 is the broadcast address

For routing, yes.  For DNS, no.


GW> I do my DNS manually, but if your using the GUI when you are done
GW> Your in-addr.arpa file (pri.248-29.189.126.202.in-addr.arpa) would look
GW> something like;
GW>
GW> ; ZONE: 248-29.189.126.202.in-addr.arpa

Zone must match the CNAME used in delegation.  Otherwise your
zone file looked good.
