Option to specify the Broker

broker => $host[:$port]

This option specifies the Broker from which the domain details are to be lifted. The string consists of a hostname or IP address followed by an optional port number, delimited by a colon. The section “Conventions for specifying IPv6 addresses” on page 108 describes how to specify an IPv6 address.

The default host is localhost, and the default port is 426.
