-- @usage nmap --script whois-domain.nse <target>
--
-- This script starts by querying the whois.iana.org (which is the root of the
-- whois servers). Using some patterns the script can determine if the response
-- represents a referral to a record hosted elsewhere. If that's the case it will
-- query that referral. The script keeps repeating this until the response don't
-- match with any of the patterns, meaning that there are no other referrals and
-- prints the output.
