subdomainLookup - Find subdomains using Google

subdomainLookup is a python script that uses Google search results to find subdomains of the target domain name.

I have been using it in security assessments and it works pretty well. Essential for network mapping. Test your own domain and see the results.

Sample usage:
> subdomainLookup.py blogger.com
beta.blogger.com
www.blogger.com
draft.blogger.com
www2.blogger.com

Download subdomainLookup v0.4 from here
* Uses main Python libraries. Tested with Python 2.5.x on Linux and Windows.

Update: Bedirhan sent me some patches that improve the results of the subdomainLookup v0.2 script. With some tests and additional improvements, here is the new version, 0.4 which can be downloaded from the same location.
