For one to be able to create multiple logical networks within a Class A, B, or C network, one needs to know the principle of subnet. Without using subnets, one could only use a single network no ...

The mask Class A subnet masks must start with 255.0.0.0 at a minimum, because the whole first octet of an IP address (the IP address describes the specific location on the network) is used to define ...

Subnetting a Class C network can be a tricky process to master. From MCSE to CCNA to RHCE to CNE, you'll have to know it and know it well. Todd Lammle walks you through clear instructions and ...
