This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.
11 paź 2024 · UDP is preferred for applications prioritizing speed and low latency over perfect reliability. Common UDP ports include: DNS (port 53): Domain Name System used for domain name resolution. DHCP (port 67): Dynamic Host Configuration Protocol for issuing IP addresses. NTP (port 123): Network Time Protocol.
10 maj 2024 · The following are the three types of ports with corresponding port number ranges: • Well-known/System ports: 0 – 1023 • Registered ports: 1024 – 49151 • Dynamic/Private ports: 49152 – 65535
31 maj 2024 · Well-known network ports range from 0 to 1023. These ports are assigned by IANA and listed in RFC 1700. On most systems they can only be used by system (or root) processes or by programs executed by privileged users. Some well-known ports use TCP, some use UDP, and some can be configured to use either.
29 sie 2016 · How are local ports determined. The port number is chosen by the TCP implementation software from a range of port numbers called Ephemeral Ports. The exact mechanism for choosing the port number and the range to be used is Operating System dependent.
This is a list of Internet socket port numbers used by application communication with TCP and UDP on the Transport Layer of the Internet Protocol Suite for the host-to-host communications.
The TCP port range encompasses numbers from 0 to 65535, offering a vast array of communication channels for various applications and services. Understanding how to configure and manage port ranges is essential for optimizing network traffic and security.
