domain check dillema

[r4nd0mch4r]

Hi, I just wrote a real small script for verifying a domain name avalibility and it's working fine.

The thing is, it checks 1 domain @ a time. I was thinking of creating a loop, that'll check several times for different extensions... like this:

-check for bla.net, return yes/no,
-check for bla.com, return yes/no,
-u get the picture...

is there any other way so I can get all the results (for all the extensions) at once? So i dont connect to the server that often...

checkdnsrr() will not verify that a domain is available. A domain may be registered, but not implemented in DNS.

However, TTT has a good idea, because if a domain is in DNS you can be sure it is NOT available, and you can skip the process of checking with a registrar. DNS is much, much faster than whois.
