>Description:
whois(1) supports both IPv6 connection and IPv4 connection.
If whois server has IPv6 address, whois(1) will try to connect IPv6 protocol first.
And if cannot connect to server on IPv6, try to connect IPv4.
If whois server has no IPv6 address, whois(1) will try to connect IPv4 connection without IPv6 coonnection.
