    la fashion wholesale jewelry Port can be divided into 3 categories:
    1 The recognized port (Well Known Ports): from 0 to 1023, they are closely bound to some services. Generally, the communication of these ports clearly shows the agreement of a certain service. For example: Port 80 is always http communication.

    2 Registration port (Ports): from 1024 to 49151. They are loosely bound to some services. In other words, many services are bound to these ports, which are also used for many other purposes. For example: many system processing dynamic ports start from about 1024.

    3 dynamic and/or private port (Dynamic and/or Private Ports): from 49152 to 65535. Theoretically, these ports should not be allocated for services. In fact, machines usually allocate dynamic ports from 1024. But there are exceptions: SUN's RPC port starts from 32768.
