Do CIDR subnets still adhere to classes?

Oct 18, 2005 3 Replies

ie. could I assign a "class A" address in the "class C" range?


294.0.0.0/8 (A class A size block of IP's in class C IP space)

Is there such thing? Or do I have to adhere to both classful and CIDR boundries when assigning IP addresses?



Thank much, Blimpie


The goal of CIDR is to increase the scalability of routers by aggregating multiple consecutive networks into a single entity (supernetting), such that only one route is required for the whole entity, rather than one route for each network. The aggregation does not need to consider any network class boundary (i.e. 204.0.0.0/8 is allowed). However, the consecutive range of network numbers must be allocated to the same authority, so that the networks within the range can share the same route.

It was a typo, was supposed to be:

204.0.0.0/8

So, when did class C networks go all the way up to 294 ?
