Hi,

I was writing a quick program to check a domain's validity and ran across
something strange which I'm not sure is a bug.  The following is a unix
shell session.

continuum:~$ host -t ns ca.
ca                      NS      clouso.risq.qc.ca
ca                      NS      ns2.uunet.ca
ca                      NS      ns3.utoronto.ca
ca                      NS      rs0.netsol.com
ca                      NS      merle.cira.ca
ca                      NS      relay.cdnnet.ca

host -r -t ns wapvi.bc.ca. ns2.uunet.ca
wapvi.bc.ca             NS      odyssey.cm.nu
wapvi.bc.ca             NS      continuum.cm.nu
wapvi.bc.ca             NS      wapvi.cm.nu
host -r -t ns wapvi.bc.ca. ns3.utoronto.ca
wapvi.bc.ca NS record currently not present at ns3.utoronto.ca
host -r -t ns wapvi.bc.ca. rs0.netsol.com
wapvi.bc.ca             NS      wapvi.cm.nu
wapvi.bc.ca             NS      odyssey.cm.nu
wapvi.bc.ca             NS      continuum.cm.nu
host -r -t ns wapvi.bc.ca. merle.cira.ca
wapvi.bc.ca             NS      odyssey.cm.nu
wapvi.bc.ca             NS      continuum.cm.nu
wapvi.bc.ca             NS      wapvi.cm.nu
host -r -t ns wapvi.bc.ca. relay.cdnnet.ca
wapvi.bc.ca NS record currently not present at relay.cdnnet.ca
host -r -t ns wapvi.bc.ca. clouso.risq.qc.ca
wapvi.bc.ca             NS      continuum.cm.nu
wapvi.bc.ca             NS      wapvi.cm.nu
wapvi.bc.ca             NS      odyssey.cm.nu

Why would some of the .ca authorative servers give a negative response on an
existing .ca zone?  Wouldn't that mean some DNS lookups would come back
negative or am I not reading this correctly.  Note: At the time of this
writing, the servers themselves appear to be up.

continuum:~$ host -r -t soa ca. relay.cdnnet.ca.
ca                      SOA     relay.cdnnet.ca admin-dns.cira.ca (
                        2002021618      ;serial (version)
                        1800    ;refresh period (30 minutes)
                        900     ;retry interval (15 minutes)
                        4233600 ;expire time (7 weeks)
                        3600    ;default ttl (1 hour)
                        )
continuum:~$ host -r -t soa ca. ns3.utoronto.ca.
ca                      SOA     relay.cdnnet.ca admin-dns.cira.ca (
                        2002021618      ;serial (version)
                        1800    ;refresh period (30 minutes)
                        900     ;retry interval (15 minutes)
                        4233600 ;expire time (7 weeks)
                        3600    ;default ttl (1 hour)
                        )

Shane
