world 3.1.1

This script takes a list of Internet top-level domain names and prints out where in the world those domains originate from. For example:

$ world tz us
tz originates from TANZANIA, UNITED REPUBLIC OF
us originates from UNITED STATES

Reverse look ups are also supported:

$ world -r united
Matches for "united":
  ae: UNITED ARAB EMIRATES
  gb: UNITED KINGDOM
  tz: TANZANIA, UNITED REPUBLIC OF
  uk: United Kingdom (common practice)
  um: UNITED STATES MINOR OUTLYING ISLANDS
  us: UNITED STATES

Only two-letter country codes are supported, since these are the only ones that were freely available from the ISO 3166 standard. However, as of 2015-01-09, even these are no longer freely available in a machine readable format.

This script also knows about non-geographic, generic, USA-centric, historical, common usage, and reserved top-level domains.
