Port 0 is reserved by IANA, it is technically invalid to use, but possible. It is sometimes used to fingerprint machines, because different operating systems respond to this port in different ways. Some ISPs may block it because of exploits. Port 0 can be used by applications when calling the bind() command to request the next available dynamically allocated source port number. |
