Hello actually this is not a problem/question/bug/error/etc...
This is a matter of curiousity
There are been very popular, the "Name Server Spy" sites, where you give some functional Name Server, and get a list of all domains that NS has.
Two sites for example (to try your self):
(you must creat an account here)
(Google NS Spy or name server spy, and find many others)
Then the question is...
IS there any Linux command/port, you can run to connect to the server NS (telnet session maybe), and get the info of the domains that are resolved by that server?
Some where, I read that a way to do this, is some how getting a list of all domains in the net, and simply run a query from those that accomplish the NS requested. But if so... then ... Is there a place/way to obtain that huge domain list? any way to connect to the root NS servers, and get that data?
And other ideas how to accomplish this?
