Niall my problem is the name server that delegated the reserve does look up the

I have this in the zone,
DNAME 0/24

0/24 NS ns.someserver.com

At the ns.someserver.com the looks ups work with no problems. However at the
main name server the PTR look up does not work.
Not sure what im missing.
You have been already advised to avoid the ".0/24." NONSENSE. You can
easily delegate x.x.x.IN-ADDR.ARPA without putting useless (and as you
report, problematic) subdomain ".0/24." there...

But the looking up the record on ns1.someserver.com works fine.

I have a few /24 that I want to delegate using DNAME.
Are you expecting to save yourself trouble by doing so?
If not, you should probably reconsider.

Don't be distracted by RFC2317. It describes the trickery you need
when you're dealing with a longer prefix (fewer addresses) than a
/24. If you have "a few /24", you can deal with them without
needing any of that.
