        So, of the 57,887 visable servers, 4314 are improperly configured 
        in the visable in-addr.arpa. tree.  Thats 7.45% of the
        servers being "not well maintained". 

a 92.55% reliability rate is not exactly impressive, at least not in
a favorable sense.

it might be tolerable if a failure of the PTR lookup doesn't cause
the application to fail. but after all, people are saying that DNS
is good enough to serve as a means to map endpoint identifiers
to realm-local addresses or routing goop.  if applications were 
written to depend on DNS reverse lookups in order to get endpoint
identifiers of their peers, they would only work as reliably as DNS,
which isn't very good.

thanks for backing up my assertion with hard data.
