I am trying to get a 3 letter domain with .net or .org and it seems like EVERY combination is taken. Is there a way i can get a list of domains available? perhaps with a bot? (i'll write it if i need to)

I can't find it, but I remember seeing an article on slashdot or something a few years ago saying that all of the 3 letter domains where used for .com, .net, and .org. –  Zoredache Jan 3 '10 at 9:16

On windows you can use

nslookup <domain name> 


C:\>nslookup abc.com
Server:  pd1nsc1.st.vc.XXXXX.net
Address:  64.59.144.XX

Non-authoritative answer:
Name:    abc.com

Example no domain:

C:\>nslookup abceeeeeeeeeeeeeeeeeeeeee.com
Server:  pd1nsc1.st.vc.XXXXX.net
Address:  64.59.144.XX

*** pd1nsc1.st.vc.shawcable.net can't find abceeeeeeeeeeeeeeeeeeeeee.com: Non-ex
istent domain

Every 3 letter domain has been registered on .com, .net, .org... I believe its the same with 4 letter domains, i think there is still some 5 letter domains left.

Asking for all three-letter domains from the .com, .net, and .org servers should take about 17576 queries to each, so 52,728 total. Should take about 15 minutes to write the script, and a few minutes to run.

It won't get you exactly what you want, as not being in DNS does not exactly mean it is free. However, it's a good start.

I have no idea how to properly check if a domain is registered or not. –  acidzombie24 Jan 3 '10 at 8:26
Use a registrar lookup, perhaps 'whois' or the like. Most places that let you register domains will let you query interactively. Asking the DNS servers, however, will be a fast filter to know what MIGHT be free. –  Michael Graff Jan 3 '10 at 8:29

You should expect that all three-letter domains are taken and many are available for sale. Google is your friend (or perhaps not).
