Okay, now I am really confused.  walma.org is registered with internic.ca, and 
ns1.walma.org is specified, together with my static ip, as the primary dns 
server.  Querying the authoritative root servers for the 'org' tld for 
walma.org gives the correct name server name (ns1.walma.org) and ip 
information (

If I understand you, you are suggesting that I need to go through a separate 
registration process for my name server?  Or was my registrar supposed to 
have done it on my behalf?  I was under the impression that since I host the 
authoritative name server for the walma.org domain, I could create 
sub-domains and distinct hosts as I please.  No?

I certainly admit that 'whois ns1.walma.org' fails, but I've never registered 
the domain 'ns1.walma.org' only 'walma.org'.
