.B \-T types
types is a comma separated list of object types.
requests the server to only send back objects that match one of the "types".
By default, whois connect to whois server both IPv6 and IPv4. If you want
to connect IPv4 only, you use
.B \-4
option, and if you want to connect IPv6 only, you use
.B \-6
option.

whois connections.
This whois is get the all of host's Information from nameserver, and
connect order is
.Pq if exists
IPv6 addresses of server at first and IPv4 address is later.

.Sh BUGS
Most of the extra flags are ONLY supported by the RIPE whois server,
or copies of the same version of the software. Usage of these flags
may cause errors on other whois servers.
.Nm
depends on
.Xr getaddrinfo 3
functions and search order depends on the function.
