My BIND 9.4.0b2 resolver did find it, but it took very long, almost
timed out.

host_look("70.84.228.226","carnival-sa.com","1179968738").
host_name("70.84.228.226","e2.e4.5446.static.theplanet.com").

But they do.

I guess fixing your zone record on NS*.DATA20.com will do it.

If the right somethings happen to be in your cache then you
may be lucky to. I would not rely on that.


 > natnum NS1.DATA20.com
host_look("64.74.223.9","NS1.DATA20.com","1078648585").

 > natnum NS2.DATA20.com
host_look("64.74.223.9","NS2.DATA20.com","1078648585").

That is not good. Your glue and DNS give different answers
for NS1.DATA20.com and NS2.DATA20.com

I guess that is the real problem.
