 This is a helper tool to be installed via `composer global` to machines where the localhost deployment process of
 Docker composition (via `docker-compose.yaml`) is prepared in a way that it binds the ports on IP from localhost subnet block and multiple of such
 compositions should be allowed to run in parallel (differentiated by the IP).
