Port Number List Well-Known Port Numbers
A port number is used to mark a port. There are 65536 port numbers in total, and they range from 0 to 65535. Why are there 65536 port numbers? Because there are 16 bits in the source and destination port fields in the TCP and UDP protocol headers respectively, so the number of port ...
There are different types of port numbers: Well Known Ports (Numbers 0 to 1023), Registered Ports (Numbers 1024 to 49151) and Dynamic or Private Ports (Numbers 49152 to 65535). The last porn number type Dynamic or Private Ports will not appear on our list because they are cannot be regis...

例如,对于每个TCP/IP实现来说,FTP服务器的TCP端口号都是21,每个Telnet服务器的TCP端口号都是23,每个TFTP(简单文件传送协议)服务器的UDP端口号都是69。任何TCP/IP实现所提供的服务都用知名的1~1023之间的端口号。这些知名端口号由Internet号分配机构(InternetAssignedNumbersAuthority,IANA)来管理。
•69 TCP port for TFTP. This port is used for configuration and upgrading the Jetdirect firmware. •80 TCP port for HTTP for EWS (Embedded Web Server). HP Jetdirect devices have an embedded Web page in the firmware which can be accessed through this port. The Embedded Web Server page ...
The Ports and protocols section includes a table that summarizes the information from the System services ports section. The table is sorted by the port number instead of by the service name. Use this section to quickly determine which services listen on a particular port.This...
