Slightly related: does anyone know how they found all the domains that were hosted on that IP? I've tried a couple of online tools, entering '119.70.119.30', and none seem to return anything.
But none of these tools could find details of the above mentioned IP!
dig @<myDnsServer> -x 119.70.119.30
No dice on any of them. Also, I was under the impression that most times there's only one PTR record for a given IP, which means you'd get at most one domain name. Not sure about that, though.
