Domainalyzer

This is a simple tool which takes a list of domain names (deduped, please) and looks up

1. Is it even registered
2. Is it resolvable
3. If so, what organization name does the apex's IP resolve to

UI:

./domainalyzer -c 5000 -o results.tsv < input.txt

Where -c gives the level of concurrency to sustain.

Input: STDIN, with entries that look like

domain

Output: overwrites the file given in argv[0], setting the .csv header with names

Requirements

You'll need a copy of GeoIPASNum.dat in your working directory, available from MaxMind.

To build, you also need the geoip C library. On OSX, brew install geoip.
