- Close the port if nothing on the host needs it.
- Identify the process that listens on it (commands below) before opening it in a firewall.
- Expose a service only to the networks that use it.

Which program uses port 7563, and is it reachable?
Linux
sudo ss -ltnup 'sport = :7563' # process listening on 7563
sudo lsof -nP -i :7563macOS
sudo lsof -nP -i :7563
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 7563 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 7563 netstat -ano | findstr :7563
From another machine
nmap -p 7563 -sV <host> nc -zv <host> 7563

What is port 7563 used for?

Is port 7563 TCP or UDP?
Port 7563 is registered for TCP.
Is it safe to open port 7563?
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 7563 is open?
On Linux run "ss -ltnup 'sport = :7563'", on macOS "lsof -nP -i :7563", and on Windows "netstat -ano | findstr :7563" to see the local process. From another machine, "nmap -p 7563 <host>" shows whether it is reachable.
