URL Formats

The URLs advertised by Communications Server consist of two parts: the dotted-decimal IP address and a port number.

A URL is an ASCII string with the following format:

<IP address>:<port number>

The IP address is the default IP address for the server. The port number depends on the service type being advertised:
