Subnet broadcast question

hello i have question about subnetting.When i have an ip =172.162.255.255 it means sending paackets in all hosts in subnet just like for example 172.16.5.255 means all hosts in subnet 5 ?or it is all hosts in all subnets?
2) what is the difference of 255 subnet and 254 (except that subnet 255 it has lagerst value in netwrok) thanks very much

What subnet mask are you working with?

clarson

a host address that is all 1's is the broadcast address for the network it belongs.

I'm sure the question makes sense to you. But, supplying an ip addresses without the subnetmask. then, talking networks and hosts makes no sense to anyone else.
