domainbrute
A basic python subdomain Domain finding tool
Other tools I found were painfully slow - some taking an hour to check for domains based on a large list, so I thought I would make one which is slightly faster.
usage - python domain.py domain.com
This simple program will spawn some threads and do a NSlookup on the domain name to find subdomains
currently it uses the GSSEC discovery list of common sub domains (114607 entries)
WARNING - to speed things up - it tries to create as many threads as it can - using Memory and CPU - it then takes a while to close down and kill all the spawned threads.
normally take about 2/3 Mins on my laptop to check the list against a domain.
TODO
Better output Export Output allow parameters such as define number of threads counter of number of entries
