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

Or get fancy and change the output type to RPSL or Cymru

$ whois -h whois.pwhois.org "type=rpsl"

Newer whois clients may require a syntax more like:

$ whois

To display a full explanation of the syntax and advanced features, simply ask for help:
