Domain Names Are Fun
I had fun with domain names tonight. I wanted to find all 4 letter domain names that start with pb that were available. I tried doing a whois lookup for each one, but that never would work right, so I just did a DNS lookup for each one. If it didn't resolve, I assumed it was available. Not a very great test, but it did cut down 4 letter domains down nearly 500 and 5 letter domains down a couple thousand.
One thing I didn't account for was shown for pbusa.com. pbusa.com doesn't resolve, but www.pbusa.com does.
Got 100 domains:

A lot of these are taken. Doing a whois will let you check if it's been taken or not.
Next up, 5 letter domains. 15487 entries.

Let's find which ones contain words using valid Scrabble words.
672 entries.

Here's what I used to check them:
checkdomains.py (This is for 5 letter. Removing the innermost loop and changing domain will do 4. Done for OpenDNS, since for domains that don't resolve, it'll give back ash.guide.opendns.com)

wordparse.py (Changes the Scrabble copy and paste to a 1 row file and then checks it against domains. And yes, the inner loop runs a ridiculous amount or times. 15037877 times to be exact. Should've kept a counter and such, but I did it really quickly and didn't worry about the extra clock cycles)
