Server Not Authoratative

[Eric Pancer]

I'm curious to know why my server isn't authoratative for the domain 
catastrophe.net <http://catastrophe.net>.
For instance....

$ nslookup
> server ns1.catastrophe.net <http://ns1.catastrophe.net>
Default server: ns1.catastrophe.net <http://ns1.catastrophe.net>
Address: 2001:4830:2280::53#53
> set type=soa
> catastrophe.net <http://catastrophe.net>
Server: ns1.catastrophe.net <http://ns1.catastrophe.net>
Address: 2001:4830:2280::53#53

Non-authoritative answer:
catastrophe.net <http://catastrophe.net>
origin = ns1.catastrophe.net <http://ns1.catastrophe.net>
mail addr = root.catastrophe.net <http://root.catastrophe.net>
serial = 2005091103
refresh = 7200
retry = 900
expire = 1814400
minimum = 10800

Authoritative answers can be found from:
catastrophe.net <http://catastrophe.net> nameserver =
ns2.catastrophe.net<http://ns2.catastrophe.net>
.
catastrophe.net <http://catastrophe.net> nameserver =

.
catastrophe.net <http://catastrophe.net> nameserver =
ns1.catastrophe.net<http://ns1.catastrophe.net>
.
ns1.catastrophe.net <http://ns1.catastrophe.net> internet address = 
207.227.243.194 <http://207.227.243.194>
ns1.catastrophe.net <http://ns1.catastrophe.net> has AAAA address 
2001:4830:2280::53

[etc..]

Is this a problem with nslookup? Or would there be some configuration that 
I'm missing?

I'm fairly certain my config is correct, so I don't understand what's up.

thanks in advance!
