This article's use of external links may not follow Wikipedia's policies or guidelines. |
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.
