a request for service to a server computer, the requested service is identified by a service or
port number. This number appears as the destination port number in the transmitted IP
packets. For example, a packet that is sent with the destination port number 80 is an HTTP
(web server) request.
The service numbers for many common protocols are defined by the Internet Engineering
Task Force (IETF at http://www.ietf.org/) and published in RFC1700, "Assigned Numbers."
Service numbers for other applications are typically chosen from the range 1024–65535 by
the authors of the application. Although the modem router already holds a list of many service
port numbers, you are not limited to these choices. You can often determine port number
information by contacting the publisher of the application, by asking user groups or
newsgroups, or by searching.
