Notes

The format of P4PORT on the Perforce client is host:port, or port by itself if both the Perforce client and server are running on the same host. Port numbers must be in the range 1024 through 32767.

If you specify both an IP address and a port number in P4PORT, the Perforce server ignores requests from any IP addresses other than the one specified in P4PORT.

To use the default value perforce with a Perforce server, define perforce as an alias to the host running the server in /etc/hosts on UNIX, or in %SystemRoot%\system32\drivers\etc\hosts on Windows, or use DNS.

If your network environment and Perforce Server have been configured to support Zeroconf services, you can set P4PORT to the value of the service name.
