Hmm, I kind of want to play digdug now:(
If you have an IP you’d like to perform a reverse lookup on to find the domain associated with it, look no further than the very light and informational dig program:
dig +noall +answer -x 188.8.131.52
Note that PTR records are not required for IP addresses. If a PTR record is not defined for an IP address, you cannot do a remote DNS lookup.
