I think he did this because he made the mistake of using nslookup in the 
first place.  It confusingly says "Authoritative answers can be found 
from: c.footprint.net", suggesting that this is the hostname of a 
nameserver.  But in this case, the Authority section of the reply 
doesn't contain an NS record, it contains the SOA record for the zone 
c.footprint.net.

Use dig instead of nslookup, and you're less likely to be confused by 
misleading output.
