  1. In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic. Some ports have numbers that are assigned to them by the IANA, and these are called the well-known ports which are specified.
  2. The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. 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

  4. Official: Port is registered with IANA for the application.[5] Unofficial: Port is not registered with IANA for the application. Multiple use: Multiple applications are known to use this port. Well-known ports The port numbers in the range from 0 to 1023 are the well-known ports or system ports .[6] They are used by system processes that provide widely used types of network services. On Unix.
  5. Well-known Ports: 0 to 1,023: These port numbers are reserved for common or popular services and applications such as web browsers, email clients, and remote access clients. Defined well-known ports for common server applications enables clients to easily identify the associated service required. Registered Ports: 1,024 to 49,151: These port numbers are assigned by IANA to a requesting entity.

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 Ports in the Well Known Ports range (0-1023) are also available for registration through IANA. Because the Well Known Ports range is both the smallest and the most densely allocated one, the bar for new allocations is higher than that for the Registered Ports range (1024-49551). A request for a Well Known port number must document why a port number in the Registered Ports of Dynamic Ports.

Well Known Ports Die Well Known Ports werden durch die IANA vergeben. Sie werden benötigt, um die höheren Protokolle von TCP bzw. UDP aus adressieren zu können. Lange Zeit wurden hier nur die Werte 0 bis 255 vergeben. Seit einigen Jahren wurde der Bereich bis 1023 geöffnet. Darüber (d.h. >1023) befinden sich die sog. Registered Port Numbers. Eine Übersicht der von Trojanern häufig. The Well Known Ports are assigned by IANA and cover the range 0-1023. On many systems, they can only be used by system (or root) processes or by programs executed by privileged users. Registration requests for a Well Known port number MUST follow the IETF Review policy of . Registrations for a port number in this range MUST document why a port number in the Registered Ports range will not. The well-known ports are defined by convention overseen by the Internet Assigned Numbers Authority (IANA). In many operating systems special privileges are required for applications to bind to these ports because these are often deemed critical to the operation of IP networks. Conversely, the client end of a connection typically uses a high port number allocated for short term use, therefore. IANA also maintains the registries which store service names and port numbers. The port registries for transport protocols are divided into three number ranges: those for System Ports, User Ports and Dynamic/Private ports. Their associated number ranges are: System Ports (0-1023) User Ports (1024-49151) Dynamic / Private Ports (49152-65535) For services to work effectively, hosts that run them.

Port numbers from 0 to 1023 are called well-known ports and are reserved for specific TCP/IP application services. The range of port numbers from 1024 to 49151 are the Registered, also known as User ports. These ports are assigned by IANA for specific service upon application by a requesting entity. The range 49152-65535 are above the registered ports. This range is reserved for the Dynamic. These ports fall within the range 1,024 to 49,151 and have been registered with the IANA in the same way the well known ports have. Most of these are not as commonly used as the well-known ports. The key difference is that unprivileged users can bind to these ports and thus run the services on their registered port. Users cannot do so on most platforms for well-known ports, since they reside. The well-known ports are defined the Internet Assigned Numbers Authority (IANA).
