Typical TCP ports
A port is a numerical address within a device which, together with the IP address, is used to uniquely identify network connections.
Each TCP port is identified by a port number (between 0 and 65535).
Ports are categorised as follows:
- Well-known ports (0–1023): For well-known services such as HTTP (port 80), HTTPS (443), FTP (21) and SMTP (25).
- Registered ports (1024–49151): For user-defined or registered applications.
- Dynamic/private ports (49152–65535): For temporary connections, e.g. in the case of client requests.
Depending on the configuration, the following typical ports are used within the visual energy system:
Number | Service |
|---|---|
25 | SMTP |
80 | HTTP, MSMQ via HTTP |

443 | HTTPS, MSMQ via HTTPS |
