| 2.4 CNAME records
| 
|    A CNAME record is not allowed to coexist with any other data.  In
|    other words, if suzy.podunk.xx is an alias for sue.podunk.xx, you
|    can't also have an MX record for suzy.podunk.edu, or an A record, or
|    even a TXT record.  Especially do not try to combine CNAMEs and NS
|    records like this!:
| 
|            podunk.xx.      IN      NS      ns1
|                            IN      NS      ns2
|                            IN      CNAME   mary
|            mary            IN      A       1.2.3.4
| 
|    This is often attempted by inexperienced administrators as an obvious
|    way to allow your domain name to also be a host.  However, DNS
|    servers like BIND will see the CNAME and refuse to add any other
|    resources for that name.  Since no other records are allowed to
|    coexist with a CNAME, the NS entries are ignored.  Therefore all the
|    hosts in the podunk.xx domain are ignored as well!
| 
|    If you want to have your domain also be a host, do the following:
| 
|            podunk.xx.      IN      NS      ns1
|                            IN      NS      ns2
|                            IN      A       1.2.3.4
|            mary            IN      A       1.2.3.4
