A few days ago I had some time left to have a look at Python (no I’m not talking about the snake 
). I tried to get time for that for months and now it happened and because Python is really good for network programming stuff I remembered a friend of mine who asked me if I know a tool to get the subdomains of a website and then I had to say that I don’t know one. So, this became my first small Python project and it’s just a tool which reads some usual subdomain names out of a wordlist and tries if some of them exists. Just as I said this is my first step in Python so the code is very ugly, simple and short but for all of you who want to have a look on it or try it out, you can just download it.
Download the Subdomain Scanner now
You can use it like this:
python subdomain_scanner.py disenchant.ch test.txt
Even if it’s nothing special at all, it’s very useful and in my tests it was amazing how many times my small wordlist matched with a interesting subdomain. Enjoy it 
Have you heard of fierce?

Hi r21vo,
of course I’ve heard and also tried out fierce but until today I haven’t read the sentence “it attempts to ‘guess’ names that are common amongst a lot of different companies” in it’s description and soI thought that this is a functionality which’s not supported but now I can just advise people to use fierce because it’s really cool and at least for me, I had my fun with my first few lines of Python code, so it’s a happy end for everyone
