What means (preferably cross-platform) can be used to display all available PCs on the local network?

Question

PostgreSQL

I welcome everyone! What means (preferably cross-platform) can be used to display all available PCs on the local network? Well, or even does PostgreSQL have standard tools for discovering available local machines on which PostgreSQL is deployed?
You can, of course, just ping addresses in a certain range, but there are certainly good ready-made solutions to the problem.
Thank you.

Answer 1

Take the network mask and go ahead, scan with pens. But ready-made solutions are unlikely to be found.

Answer 2

In general, no

Answer 3

nmap -v 192.168.0.*

Answer 4

nmap -sP 10.0.0.0/24 - all live hosts on network 10.0.0.0/24
