Re: UDP broadcasting ?

Hi everybody,

We have an embedded system, which is on a network and whose IP address can be changed using an interface. Now, would it be possible to send UDP broadcast from another machine and the embedded system to reply, so that we can know that the system is on the network and know its IP address ?

Yes, various devices and software have used this for years.

From what I know, UDP broadcast will only work on the same subnet, but what if the embedded system is on another subnet?

Then I would use multicast instead. Multicast was designed to cross routers.
