What is a proxy port?: definition, mechanism, reproducible checks, and what it means for dedicated static residential operation.

The port is the number on the endpoint host that accepts your connection - half of the address pair.

How it works, step by step

  1. 1

    Direct definition

    The port is the number on the endpoint host that accepts your connection - half of the address pair.

  2. 2

    How it works

    Host + port locate the service; credentials authenticate it. Wrong port means refusal.

  3. 3

    Static-residential implication

    Host and port are fixed for the endpoint's life; record them in the map.

  4. 4

    Reproducible check

    Probe the endpoint port from your machine; open means reachable.
