Hi Guys,
I know this is a bit off topic, but im not having any luck googling it.
I want to know where I can go programatically to get a list of all
registered domains on the internet.
Cheers

No, i mean is there a way to retrieve a list of domain names from the DNS
server and display them in a database using vb.net.
i was also wondering if it is possible to find the domain name by resolving
it with the ip Address, not sure if that is possible but
any help would be much appreciate .
Thanks Guys.
So, you want to programmaticall y build what a DNS server already does?

yes, i am building a crawler which returns the links on a website and stores
them in a database, i am trying to get domain names by
testing to see if i can resolve the ip address, incrementing them by one
each time until it hits a domain, it then stores in a database
and can be used later.

"A list of domain names from the DNS server" doesn't make any sense to me.
Dig is the most versatile DNS client I know (that is, it's better than
nslookup or library calls). Take a look at the man page. It'll give you an
idea of how DNS is expected to be indexed. As far as I know, domain lists
don't exist in a single source. You could call DNS the first federated
database I suppose. If you want to know all the delegates of a given
authority, well, again, I don't think you can even get that.
You can pull A records to your hearts content tho.
i was also wondering if it is possible to find the domain name by
resolving it with the ip Address, not sure if that is possible but
Besides being a living thing, FQDNs and dotted quads are a many to many
relationship. You can also map dandeliones in your neighborhood. I
question the wisdom of both. :)
any help would be much appreciate .
Thanks Guys.

The only reliable way to do this is to linearly query each possible domain
name starting with a.com, a.net, a.org.. etc.. and ending with
zzzzzzzzzzzzzzz zzzzzzzzzzzzzzz zzzzzzzzzzzzzzz zzzzzzzzzzzzzzz zzzzzzzzzzzzzzz zz.com,
..org, etc... (actual maximimum length is probably much longer, that was
just an example).
Unless you have serious bandwidth, and lots of machines to do simultaneous
work, it's not likely you would complete this task in any decent timeframe,
and likely by the time you finished it would be out of date anyways, as
domains expire or are bought daily.
Just a quick note here. The Original Post Was made by my Son on my machine.
Just wanted to clear this up. He is sixteen and trying to find out about the
internet and wants to use .net to do it.
Having said this, his question is an interesting one, im not quite sure how
crawlers get notification of newly registered domain names in order to crawl
them.
Does anyone know ? It would seem to me that the DNS servers have all the
information one needs, its just about how to get it ?

They don't get notification. They have to just query dns for all possible
name combinations. Unless of course they have some kind of backdoor deal
with a registrar (or someone that works for one). But even then, they'd
only know about accounts registered through that registrar.

No. DNS is a distributed architecture. The root DNS servers do have all
possible domain names in them, but they just defer to whatever DNS server
is defined for that name to provide everything else. This is a query-only
service. You have to know what you're looking for to get an answer. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi all. I've got an app that dumps a user id into a session after
successful login. the login page is http://www.mydomain.com/login.php.
If the user visits pages on my site without the www (i.e.,
http://mydomain.com/foo.php), the session works fine and login state is
maintained.
If he visits http://www.mydomain.com/foo.php, the app drops the
logged-in state.

While I agree with the sentiment, the oringinal title on this thread
("OT: Specially for , why you should always use example.com

The search for reserved domain names should start with RFC 2606
