It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 43210 is open?

On Linux run "ss -ltnup 'sport = :43210'", on macOS "lsof -nP -i :43210", and on Windows "netstat -ano | findstr :43210" to see the local process. From another machine, "nmap -p 43210 <host>" shows whether it is reachable.
