List of TCP and UDP port numbers
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 well-known ports.
Port (computer networking)
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.A port at the software level is identified for each transport protocol and address combination by ...
Service Name and Transport Protocol Port Number Registry
SCTP. Service names are assigned on a first-come, first-served process, as. documented in [ RFC6335 ]. Port numbers are assigned in various ways, based on three ranges: System. Ports (0-1023), User Ports (1024-49151), and the Dynamic and/or Private. Ports (49152-65535); the different uses of these ranges are described in.
TCP and UDP port numbers
Well-known ports. Well Known Ports (Numbers 0 to 1023) - These numbers are reserved for services and applications. They are commonly used for applications such as HTTP (web server) POP3/SMTP (e-mail server) and Telnet. By defining these well-known ports for server applications, client applications can be programmed to request a connection to that specific port and its associated service.
Well-Known TCP/IP Port Numbers, Service Names & Protocols
About TCP/UDP Ports. Port 0 to 1023: These TCP/UDP port numbers are considered as well-known ports. 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 ...
Wikiport
Wikiport provides clear explanations of how port numbers are assigned and how they interact with different protocols. Port numbers are divided into three ranges: - Well-known ports (0-1023) - Registered ports (1024-49151) - Dynamic or private ports (49152-65535) Each range serves a specific purpose and is managed by the Internet Assigned ...
RFC 7605: Recommendations on Using Assigned Transport Port Numbers
Even so, System port number assignments have continued at an average rate of 3-4 per year over the past 7 years (2007-2013), indicating that the desire to keep this distinction continues. As a result, the difference between System and User port numbers needs to be treated with caution. Developers are advised to treat services as if they are ...
What are Port Numbers, and How Do They Work?
Port numbers are 16-bit unsigned integers ranging from 0 to 65535, used to identify specific communication channels on a device connected to a network. Each application or service running on a ...
Well-known port assignments
This topic lists the well-known port assignments for transport protocols TCP and UDP, and includes port number, keyword, and a description of the reserved port assignment. You can also find a list of these well-known port numbers in the hlq .ETC.SERVICES data set. The official assignment of port numbers is managed by the Internet Assigned ...
Port Numbers Used for Computer Networks
In both TCP and UDP, port numbers start at 0 and go up to 65535. The lower ranges are dedicated to common internet protocols such as port 25 for SMTP and port 21 for FTP. To find the specific values used by certain applications, view a list of the most popular TCP and UDP port numbers. For Apple software, view the TCP and UDP ports used by ...
Well-Known Port Numbers
Well-known port numbers are assigned within the range 0 through 1023 and are specified in Request for Comments (RFC) 1060. (The total range of possible port numbers is 0 through 65535.) The following table describes some of the well-known port numbers. Well-Known Ports.

use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[5] However, many unofficial uses of both well-known and registered port

What are port numbers and how do they work?
Port numbers are part of the addressing information that helps identify senders and receivers of information and a particular application on the devices. Port numbers consist of 16- bit numbers. For example, a user request for a file transfer from a client, or local host, to a remote server on the internet uses File Transfer Protocol (FTP) for ...
Port Numbers
These port numbers include everything above under "Common Ports" until port 1433/1434, non-inclusive. These are also known as privileged ports, and root level (or Administrator on Windows) access is required to bind a process to these port numbers. Ports 1024 to 49151 are considered "registered ports". Ports 49151 to 65535 are called "dynamic ...
Internet Assigned Numbers Authority
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol-related symbols and Internet numbers. [1] [2]Currently it is a function of ICANN, a nonprofit private American corporation established in 1998 ...
What are the origins of standard port numbers?
Early on the designers of the protocols picked the port numbers and maintained a registry. Overtime these became the official numbers and people agreed to use them for those protocols and not for other programs. Eventually these became codified in the RFCs and the IANA was born to manage the process. answered Oct 16, 2009 at 13:46.
What are dynamic port numbers and how do they work?
The registries for these protocols are divided into three categories, based on the available range of numbers (0 to 65535): System ports, also known as well-known ports, include ports 0 to 1023 and support commonly used services.; User ports, also known as registered ports, include ports 1024 to 49151 and are assigned to specific services, based on service applications submitted to IANA.
