I'd like to take two parts of a class B address space, and express it in CIDR notation, if it can be done. For example, I'd like to take 192.168.130.0 and 192.168.131.0 and represent them with a ...

If you think about the underlying binary values, CIDR — the classless inter-domain routing method of expressing IP address ranges — makes a lot of sense. The trick is understanding that the boundary ...

CIDR (Classless Inter-Domain Routing or supernetting) is a method of assigning IP addresses that improves the efficiency of address distribution and replaces the previous system based on Class A, ...

Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation indicates the total number of IP addresses available. Click here to see an enlarged diagram. Understanding ...

Today, the standard methods for moving the network/host address boundary are variable-length subnet masking (VLSM) for host addressing and routing inside a routing domain, and classless interdomain ...
