Can't find Server Name error

Ok, I think I need a little help. This may be way simple or
hopelessly tangled but I've been banging around on this with
a hammer and getting nowhere.

When I try to do nslookup   -- for anything including
localhost and my correct hostname (files appended to end of
this letter) I get the following error.

[root at kumo /root]# nslookup localhost
*** Can't find server name for address 64.217.68.34: No
response from server
*** Default servers are not available
[root at kumo /root]# 


or if I nslookup some known web site like www.io.com

[root at kumo named]# nslookup www.io.com
*** Can't find server name for address 64.217.68.34: No
response from server
*** Default servers are not available
[root at kumo named]# 

I believe I have properly registered the name servers with
register.com (where I purchased the domain name. (last
night)

I have requested the ISP to delegate the reverse mapping for
my subnet. (last night)

It seems that earlier in this episode I actually had
nslookup working just fine before I registered anything.
This of course makes me think I've gorked something here.

When I restart named then check /var/log/messages all seems
ok. There is a nagging message about not finding TTL (which
seems to be there) but the log happily reports using default
value -- seems ok.

I have the slave nameserver doing it's zone transfers etc.
ok.

I'm not sure what to include here so I've got it all. These
are all real names and IP numbers -- seems that if it is a
nameserver all this stuff is there for the world to see
anyway.

I'm wondering (Santa Claus anyone) if maybe it will all
start working when register.com and my ISP's records are "up
and running".

The ISP is swbell.net
their nameservers are 
151.164.1.8
151.164.1.7

Ok, here's my dirty laundry

/etc/resolv.conf

search kndn.com swbell.net 
#nameserver 151.164.1.7
#nameserver 151.164.1.8
nameserver 64.217.68.34

(the SWBELL ns commented out while testing stuff)

/etc/hosts  if it matters
