PORT NUMBERS The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or Private Ports. The Well Known Ports Port Numbers. Description. UDP 4145. IANA approved port for heartbeat communication between the Primary and Secondary. TCP 8199. IANA approved port for communication between the vradmind daemons on the Primary and the Secondary. TCP 8989. Communication between the in.vxrsyncd daemons, which are used for differences-based synchronization. UDP Apr 08, 2004 · Here is a portion of the port numbers file at IANA: WELL KNOWN PORT NUMBERS The Well Known Ports are assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users. Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations. registered port numbers: The registered port numbers are the port number s that companies and other users register with the Internet Corporation for Assigned Names and Numbers ( ICANN ) for use by the applications that communicate using the Internet's Transmission Control Protocol ( TCP ) or the User Datagram Protocol ( UDP ). In most cases, All that this file really is is a mapping file to allow you to request a service by name (let's say "telnet", for instance) and have the system translate it to the port number (23). It is best practice when writing software to use the name, if possible, rather than the number. (Internet Assigned Numbers Authority, www.iana.org) An operating unit of the Internet Corporation for Assigned Names and Numbers (ICANN) that maintains the top-level domain, IP address and IANA coordinates the global pool of IP numbers and AS numbers (autonomous system numbers or just ASN), which are assigned in address blocks to the five regional internet registries (RIR). RIRs in turn make smaller address blocks available to the respective local internet registries (LIR) and the national internet registries (NIR) , which then

May 12, 2008 · The contact port is sometimes called the “well-known port”. To the extent possible, these same port assignments are used with the UDP [RFC768]. The range for assigned ports managed by the IANA is 0-1023. User port numbers range between 1024 and 49151. If you wish to register a system port — those numbered 1023 or less — it must be done through the standardisation process of the IETF. Designers of applications and application-level protocols may apply to the Internet Assigned Numbers Authority (IANA) for a registered port number for a specific application, and may after successful registration assume that no other application will use that port number for its communication sessions. In it Postel first proposed a registry of assignments of port numbers to network services, calling himself the czar of socket numbers. [21] The first reference to the name "IANA" in the RFC series is in RFC 1083 , published in December, 1988 by Postel at USC-ISI, referring to Joyce K. Reynolds as the IANA contact.

These ports are assigned to specific server sevice by the Internet Assigned Numbers Authority (IANA). For example, port 80 is used by web servers. Port 1024 to 49151: These are ports that an organization, such as application developers, can register with IAMA to be used for a particular service. http://www.iana.org/assignments/port-numbers. The Dynamic and/or Private Ports are those from 49152 through 65535. This is the range from where you SHOULD pick a port for your in-house applications. Of course any port belonging to one of the unassigned ranges on the published list can be used. Apr 16, 2019 · The Internet Assigned Numbers Authority (IANA) is the governing body who manages and regulates Internet Protocol (IP) addresses and Port Numbers assignments. According to the Service Name and Transport Protocol Port Number Registry of IANA, there are a total of 65,535 ports. The Internet Assigned Numbers Authority (IANA) registers ports 1024 to 49151 for the convenience of the Internet community. Port numbers from 49152 to 65535 are private ports, also called "dynamic The Internet Assigned Numbers Authority (IANA) suggests the range 49152 to 65535 (2 15 +2 14 to 2 16 −1) for dynamic or private ports. Many Linux kernels use the port range 32768 to 60999. FreeBSD has used the IANA port range since release 4.6. The Internet Assigned Numbers Authority (IANA) is a department of ICANN that is responsible for maintaining the registries of the Internet's unique identifiers, which include domain names, Protocol Parameters, and Internet numbers (IP Addresses and Autonomous System Numbers). To comply with Internet Assigned Numbers Authority (IANA) recommendations, Microsoft has increased the dynamic client port range for outgoing connections in Windows Vista and Windows Server 2008. The new default start port is 49152, and the new default end port is 65535.
