iwhois: add some improvements (thanks gall0ws) patch from gall0ws: > It's impossible to get whois right and probably nobody cares about it, > nevertheless this small patch fixes some issues with the current version: > > * use a more common filter for default boilerplate (useful when > following the referral chain) > * updated boilerplate for *.co.uk *.net.uk *.org.uk > * added case *.com *.net (got it from iana.org) > * use ARIN for IPv6 addresses > * when unsure, check first whether whois.nic.$tld exists otherwise > usual fallback to InterNIC > * fixed regexp for the referral chain (case, extra spaces or /) - add usage handling. -- cinap
