TCP ports map, range 7000-20000, biggest ports tcp/udp library database

The port numbers are divided into three ranges:
  • The Well Known Ports are those in the range 0–1023. On Unix-like operating systems, binding a communications socket to a port in this range requires administrative privileges or possessing CAP_NET_BIND_SERVICE capability.
  • The Registered Ports are those in the range 1024–49151. (list of small subranges (7000-20000) you can see in "TCP ports ranges" window)
  • The Dynamic and/or Private Ports are those in the range 49152–65535. Randomly chosen port numbers out of this range are called ephemeral ports. These ports are not permanently assigned to any publicly defined application.
This is library of TCP Port Numbers and UDP Port Numbers.
Current service contain the biggest tcp udp port list. Port search going through 4 library (database),
total number of records are about 22000 (in 3 times more that in other service).
Processes implement connections to transport protocol ports by means of sockets. A socket is the software structure used as the transport end-point. It is created by the process and bound to a socket address which consists of a combination of a port number and an IP address. Sockets may be set to send/receive data in one direction at a time (half duplex) or simultaneously in both directions (full duplex).
An example for the use of ports is the Internet mail system (e-mail). A server used for sending and receiving e-mail provides both an SMTP service (for sending) and a POP3 service (for receiving).
The most well-known from this range: 8080 Apache Tomcat, 8081 HTTP alternate, 8086 Kaspersky AV Control Center, 13724 Symantec Network Utility—vnetd (formerly VERITAS).

In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but also other protocols, use a numerical identifier for the data structures of the endpoints for host-to-host communications. Such an endpoint is known as a port and the identifier is the port number. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.
