Delegation Problems

[Patrick Hulman]

i'm seeing really weird problems when i delegate from 64 space that I own.
(64.147.0.0/19 and 64.58.128.0/19). i've delegated first at the
147.64.in-addr.arpa (and 58.64) and then later at
64.in-addr.arpa

In each case the in-addr.arpa looks like the following:

$ORIGIN 147.64.in-addr.arpa.

$GENERATE 0-24 $     NS  ns1.coxmail.com.
$GENERATE 0-24 $     NS  ns2.coxmail.com.

25             NS      ns1.smc.com.

$GENERATE 26-31 $     NS  ns1.coxmail.com.
$GENERATE 26-31 $     NS  ns2.coxmail.com.


When I do a dig +trace -x 64.147.25. i get the following
dig +trace -x 64.147.25.10

As far as I can tell I'm delegating the same in other spaces that I own
and they work fine.

Can anyone enlighten me to tell me what's happening?
