The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
Ports with numbers 0–1023 are called system or well-known ports; ports with numbers 1024-49151 are called user or registered ports, and ports with numbers 49152-65535 are called dynamic, private or ephemeral ports. [2] Both system and user ports are used by transport protocols (TCP, UDP, DCCP, SCTP) to identify an application or service.
The registered ports are those from 1024 through 49151. IANA maintains the official list of well-known and registered ranges. [3] The dynamic or private ports are those from 49152 through 65535. One common use for this range is for ephemeral ports.
32768–65535: used by Solaris OS [citation needed] and AIX OS. [citation needed] 1024–65535: RFC 6056 [6] 1025–60000: default of Windows Server 2008 with Exchange Server 2007 installed. [7] In addition to the default range, all versions of Windows since Windows 2000 have the option of specifying a custom range anywhere within 1025–65535 ...
Port numbers 0 through 1023 are used for common, well-known services. On Unix-like operating systems, using one of these ports requires superuser operating permission. Port numbers 1024 through 49151 are the registered ports used for IANA-registered services. Ports 49152 through 65535 are dynamic ports that are not officially designated for any ...
In Internet protocols, 65535 is also the number of TCP and UDP ports available for use, since port 0 is reserved. [7] In some implementations of Tiny BASIC, entering a command that divides any number by zero will return 65535. [a] In Microsoft Word 2011 for Mac, 65535 is the highest line number that will be displayed.

The principal facilities of the Port of Virginia are four marine terminals, all on ...
If this source port is already used, PAT assigns the first available port number starting from the beginning of the appropriate port group 0–511, 512–1023, or 1024–65535. When there are no more ports available and there is more than one external IP address configured, PAT moves to the next IP address to try to allocate the original source ...
