	Technically, nothing -- at least, with the absolute latest 
authoritative nameservers and the absolute latest recursive/caching 
nameservers, and it doesn't seem to give much problems to modern 
resolver libraries.

	Procedurally, everything is wrong with it -- in part, because of 
the profusion of mis-configured authoritative and recursive/caching 
nameservers that exist on the Internet today (not to mention 
resolving libraries), the fact that most vendors today still ship 
vulnerable authoritative & recursive/caching nameservers with their 
OSes (and *no one* ships an OS that uses modern resolver libraries), 
and the fact that 99.999999% of the people on the 'net will take the 
default garbage that the vendor ships to them simply because they 
don't know any better.

	They are the ones associated with your NS records.  At a 
procedural level, PTR records are mutually exclusive with SOA & NS 
records.

        See above.
