Anyone know from what data does it get such an info? By scanning every
possible registered domain ?
Could be by recording the info used by a dns resolver they manage. I
suspect lots of other ways.
I do not want other to get list of what domains my DNS server serve.
ummmm.... sorry?
that's not how DNS works. Anyone querying a domain will know who serves
that domain. Building a list is trivial. Delivering it to someone else
is trivial. Look at why you don't want people to know what you are
serving authoritative DNS for...and ask yourself why, and fix it. This
is not secret. In general, if you are hoping DNS is keeping secrets for
you, you are doing it wrong.
And this works - never gives complete list but always a good part.
thank you
what it gives is "interesting" -- I'm guessing logs from a big resolver,
a search engine, or maybe domain registration changes. Just punched up
something I thought could be interesting (a small NS, keeping a lot of
unused domains from hostiles/squatters), and it told me things I didn't
know, and other things that I think could be more public knowledge
didn't show up at all, so I'm guessing domain registration changes
(though I don't have a lot to go on there, either).
Legal? That would be kinda like telling drivers they can't make note of
where stop signs are.
