Hard to get the sense of that sentance, but I think you speak of broadcast addresses.

That depends on your netmask. For example if your netmask is 255.255.0.0 (/16), the broadcast address would be 192.0.255.255. If you ping that, you would get a response from every computer on that network.

Short calculation example:



Address: 192.0.0.123 11000000.00000000.00000000.01111011
Netmask: 255.255.0.0 = 16 11111111.11111111.00000000.00000000
Wildcard: 0.0.255.255 00000000.00000000.11111111.11111111
=>
Network: 192.0.0.0/16 11000000.00000000.00000000.00000000 (Class C)
Broadcast: 192.0.255.255 11000000.00000000.11111111.11111111
HostMin: 192.0.0.1 11000000.00000000.00000000.00000001
HostMax: 192.0.255.254 11000000.00000000.11111111.11111110
Hosts/Net: 65534

wich server, does that only work, when a server knows all other computers ?

I thought, that when the command 198.168.0.255 is sendet, that all computers in 192.168.0.1-254 send a response.

I tryed ist also with the programm ping, but i don't get responses !

196.168.*.* are local network adresses, they never get routed over the internet. So unless you have a LAN connected to your PC you won't get a reply. Anyway, I believe broadcast packets are blocked by many internet routers so don't expect that to work over the internet.
