Registered port
A registered port is a network port (a sub-address defined within the Internet Protocol , in
the range 1024–49151) assigned by the Internet Assigned Numbers Authority (IANA) (or by
Internet Corporation for Assigned Names and Numbers (ICANN) before March 21, 2001,
[1]
or by USC/ISI before 1998) for use with a certain protocol or application.
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 and/or private ports .
[2]
Both system and user ports are used by transport
protocols (TCP, UDP, DCCP, SCTP) to indicate an application or service.

Many Linux kernels use the port range 32768 to 61000.
[note 2]
FreeBSD has used the IANA port range
since release 4.6. Previous versions, including the Berkeley Software Distribution (BSD), use ports
1024 to 5000 as ephemeral ports.
[2][3]
Microsoft Windows operating systems through XP use the range 1025–5000 as ephemeral ports by
default.
[4]
Windows Vista , Windows 7 , and Server 2008 use the IANA range by default.
[5]
Windows
Server 2003 uses the range 1025–5000 by default, until Microsoft security update MS08-037 from
2008 is installed, after which it uses the IANA range by default.
[6]
Windows Server 2008 with
Exchange Server 2007 installed has a default port range of 1025–60000.
[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.
