[issue20480] Add ipaddress property to get reverse DNS name

[Leon Weber]

New submission from Leon Weber:

I was missing a method to compute the reverse DNS name for an IP address, and I felt this is something that would belong in the ipaddress module; so here’s a patch for the ipaddress module adding a reverse_name property to IPv?Address.

This is an example:

>>> ipaddress.ip_address("127.0.0.1").reverse_name
'1.0.0.127.in-addr.arpa.'
>>> ipaddress.ip_address("2001:db8::1").reverse_name
'1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.'

Would this be an acceptable feature for inclusion in the ipaddress module?
