CNAME and other data -vs- could not find NS and/or SOA records

[Jonathan de Boyne Pollard]

KD> For instance, www.foo.com could (if it is not a zone apex) 
KD> be an alias for bar.com. bar.com could (and probably would,

KD> www.foo.com/SOA, they'd get the SOA of bar.com in the response.
KD> Voila! One has "aliased an SOA record". 

A real-world example is "www.openwatcom.com.".
