Registered ports
This article's use of external links may not follow Wikipedia's policies or guidelines.
Please improve this article by removing excessive or inappropriate external links, and
converting useful links where appropriate into footnote references. (October 2011)
The range of port numbers from 1024 to 49151 are the registered ports. They are assigned by
IANA for specific service upon application by a requesting entity.[1] On most systems, registered
ports can be used by ordinary users.
This is an incomplete list of notable ports. See the Service Name and Transport Protocol Port
Number Registry of IANA for the complete list of assigned ports.
