# globetrotter

globetrotter retrieves a list of DNS servers around the world from the [Public DNS Server List](http://public-dns.tk/) and runs your query against them. This is particularly handy for compiling list of SaaS endpoint IPs in cases where the provider doesn't specify them.

## Installation

    $ gem install globetrotter

## Usage
Query 100 DNS servers for googleapis.com, making 10 requests in parallel at a time:

    $ globetrotter -q googleapis.com -c 100 -p 10
    
Write results for google.com to /tmp/google.txt - file will be created if it doesn't exist

    $ globetrotter -q google.com -f /tmp/google.txt

See `globetrotter -h` for all parameters

## TODO
* Improve command line argument parsing
* Handle non-A records
