No, but you should see them if you query for any of the addresses in the
block, e.g. "dig 233.128.68.63.in-addr.arpa any".

It doesn't look like directlink.net has implemented the RFC 2317 delegation
to you.  You need to contact them and find out why they didn't delegate it
like they said they did (they *did* tell you they delegated it, didn't
they?).
