No, the ports below 1024 are well-known ports, and the port functions have been basically determined. 1024-65535 is a dynamic port, which can be used at will in theory, but different applications sometimes have port conflicts. Most websites have 80 ports, but some are 8080, 808 1, etc. The management interface ports of some devices are set by the manufacturers themselves. For example, the dial-up port number of Freestar is 30 12.
Hope to adopt!
