Detection and Display using Javascript Options

[s3s3]

I have a LAN where several boards are connected, each having its own (known) ip adress. I am controlling them through HTML (toggling leds, reading temperature etc). I would also like to add a function which shows which board is connected, so that I don't have to check this manually. How could this be done in HTML and/or javascript?

The unintelligent way to do this is to use JavaScript to check the response of the web server.

Unintelligent means that it does not know that when the web server is down, it can still be connected to the network. Using the unintelligent method means that the only way to check would be that the web server must be online.

Is the unintelligent method acceptable to you?

Unintelligent way seems ok since if the web server on the board is down it doesnt matter if te board is still connected or not, what would I have to use in order to accomplish this "unintelligent" way? give me a starting point

And since u mentioned the unintelligent way, What would be the inteligent way to do it then?(just for the sake of curiosity)
