Javascript to find whether device is present in a LAN

How would you do that? The website synology.com seems to be able to use JavaScript to peer into your LAN to see if one of its products is connected to your network.

Pop open developer tools and it's super easy to figure out. It sends requests to diskstation.local, rackstation.local, and nvr.local.

Their products broadcast local hostnames that anyone on the same LAN can see, and this website just looks for them. If you have those products you can probably access http://diskstation.local/ or one of the others.
