Yes, the major network prefix includes all of its subnets. But once you've subnetted a prefix, you can't assign that prefix to an interface because you'll end up with overlapping network addresses.
For example, let's say you have the address 172.16.1.0/24 and want to split it into two subnets. This would give you 172.16.1.0/25 and 172.16.1.128/25. Now you take those two /25 prefixes and assign them to two separate ethernet segements. Once you've done that, you should never use the original prefix--172.16.1.0/24--because it overlaps the two new prefixes and would cause all sorts of routing problems. Each network prefix assigned to a subnet must be unique. >>> "Steven A. Ridder" 12/14/01 12:51:25 PM >>> Because the major network was subnetted, it includes all networks under it. Therefore it's the same network, just subnetted. Do I have it right?
