I'm seeing this unusual behavior with reverse DNS lookups on this public IP Address:
184.108.40.206. Can someone explain what's going on?
MXToolbox PTR lookup resolved
localhost as the domain
ping -a is even stranger; it resolved it to my local PC name (clifford):
ping -a 220.127.116.11 Pinging clifford [18.104.22.168] with 32 bytes of data:
nslookup via Google's public 22.214.171.124 DNS server also resolves it to
nslookup 126.96.36.199 188.8.131.52 Server: google-public-dns-a.google.com Address: 184.108.40.206 Name: localhost Address: 220.127.116.11
