Introduction
This Tech Note lists the most common well-known ports used by Bionic Buffalo software.
Well-known ports are assigned by IANA (Internet Assigned Numbers Authority). A complete
and current list of such ports is available at their web site, http://www.iana.org.
This document is meant to be a short, handy reference for working with our software. Unlike
the IANA list, this list is sorted alphabetically by protocol name. (IANA’s list is sorted
numerically by port number.) It is not meant to take the place of the full list from IANA.
