[DSL] rDNS and DNS
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 188.8.131.52
184.108.40.206.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 220.127.116.11
18.104.22.168.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 22.214.171.124
Anyone else noticed this?
