[DSL] rDNS and DNS

Hi all,

noticing some weird problems today when I was connecting to one of my servers (which by default was checking the IP address connecting resolved to a name which itself resolved).

~# host 108.175.231.112
112.231.175.108.in-addr.arpa domain name pointer 108-175-231-112.dsl.teksavvy.com.
~# host 108-175-231-112.dsl.teksavvy.com
Host 108-175-231-112.dsl.teksavvy.com not found: 3(NXDOMAIN)

This is different from the behaviour that previously existed where addresses resolved forwards and backwards.

~# host 76.10.141.218
218.141.10.76.in-addr.arpa domain name pointer 76-10-141-218.dsl.teksavvy.com.
~# host 76-10-141-218.dsl.teksavvy.com
76-10-141-218.dsl.teksavvy.com has address 76.10.141.218

Anyone else noticed this?
