Can the Subnet ID be used as Gateway?

I was always  under the impression that the first IP of a subnet range was the gateway and the last was the broadcast address. For example

the range is

.196 to .199

Can I use the .196 as a gateway?

so you would configure per se your router interfaces with the gateway...

.196 is your network number and can not be used. 199 is the network broadcast and can not be used. Any other number in between can be used for any device. You do not specifically need to use the first available number as your gateway but that is what a lot of people do. The key is the ip address you assign to your gateway device make sure all other devices show that ip as their gateway.

Hope this helps
njcomp3Author Commented: my I would use the .197 address and .198 address in a point to point scenario...

in no situation would i ever be able to configure a network id on any device ..correct?
That is correct, if it is a point to point then one side gets the .197 and the other side gets the .198. cisco gear will actually give you an error saying the ip address in invalid if you try to use the subnet number or the BC.
