Subnetting & Supernetting Question

[guyver01]

I understand that with subnetting, Two addresses are reserved on every network, x.x.x.0 and x.x.x.255.

Does the same hold true with supernetting?

what happens if you assign a .0 or .255 address?

I'm not sure why this is in OT instead of Networking, but anyway. That's not quite accurate. The first and last addresses in a subnet are always reserved for the network and broadcast address. Those addresses are not necessarily .0 and .255. If you have a network bigger than a /24, then yes, .0 and .255 can be perfectly valid addresses. Example:

192.168.4.0/23:

192.168.4.0 - network address
192.168.4.255 - normal IP address
192.168.5.0 - normal IP address
192.168.5.255 - broadcast address
