It shouldn't, should it? Because opensrs.net has no A record containing
the IPv4 address 216.40.33.45. 

_Anyone_ could set their own PTR records to whatever text they like, in
anyone else's domain. It's only trustworthy if there's a corresponding A
or AAAA record pointing back to the same IP address you started with.
