I'm attempting to improve my understanding of the DNS system and am confused as to how domaintools.com manages to resolve all DNs associate with an IP addr.
After playing around with dig, i'm stuck.
Example on domain dressupgames.com
using dig::
$ dig +short dressupgames.com
173.231.156.28
$ dig +short -x 173.231.156.28
28.24/29.156.231.173.in-addr.arpa.
$ dig +short 28.24/29.156.231.173.in-addr.arpa
67.215.65.132
$ dig +short -x 67.215.65.132
hit-nxdomain.opendns.com.
$ dig +short hit-nxdomain.opendns.com
67.215.65.132
Presumably 173.231.156.28 is an alias for 67.215.65.132 (?). Now using DomainTools web interface http://www.domaintools.com/research/reverse-ip/ i get the promise of 129 results.
How can i find these results using commandline tools?
