Systems equiped with our WhoB whois client (get it here) can simply type:
$ whob 220.127.116.11 18.104.22.168 | origin-as 3356 (22.214.171.124/8) | LVLT-ORG-4-8
Or, a fancy version may look like:
$ whob -npr 126.96.36.199 188.8.131.52 | origin-as 226 (184.108.40.206/23) | radb-as 13361 | Internet Media Network
To use pWhoIs with almost any whois client, simply point your favorite whois client to one of our global, public pWhoIs servers by querying host 'whois.pwhois.org'. For example:
$ whois -h whois.pwhois.org 220.127.116.11
Or get fancy and change the output type to RPSL or Cymru
$ whois -h whois.pwhois.org "type=rpsl 18.104.22.168"
Newer whois clients may require a syntax more like:
$ whois email@example.com
