ip address 192.168.1.255 is special ?

[wxuf]

hi.. suppose my local network has a network & subnetwork id 192.168.1 and the sub-network mask is 255.255.255.0, the most common case. Then the host id in my LAN is from 1--- 254.

then what is the address 192.168.1.255 ? is it used as the default router ? or something else ?

I have no idea with this problem, please help to explain, thank you !

In you case, this's a broadcast address.

hi.. you see, the ip address is consist of network id, sub-network id and host id. and the sub-network mask is used for the network id and sub-network id.
On my case the mask is 255.255.255.0 then the host id is from 1--254. the first three bytes are network id & sub-network id.
