Re: [lwip-devel] [patch #6539] ICMP broadcast

[Alain M.]

I can answer that: I didn't know of that broadcast ping, but I tested 
here on my LAN and it works. The answer is:

that is usefull for manual operation. You just go to any client machine 
and ping 10.0.0.255 and you hava a list of everything. I surely will use 
it in the future :)
