A recent posting on comp.dcom.cisco suggested that you can't
have a 7-bit subnet. For example, 188.8.131.52 255.255.254.0 should
be equal to two class C networks, but the two "subnets" would be
the all zeros and the all ones subnets. Apparently this goes against
the Host Requirments RFC. Would this be a vaild CIDR route? Thanks....
As I replied privately, I believe this will work with CIDR "supernetting"
because no "all-nets" broadcast addresses are defined. This issue may be more
sticky as we move toward a truely classless addressing plan, though - consider
a CIDR block which is carved out of a "class A" network, for example...
Anyone else care to comment?
