Frequently Asked Questions
What is CIDR?
Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing. It is represented by a slash (/) followed by a number indicating the number of bits used for the network mask.
Why is host count minus 2?
In a standard subnet, the first address is reserved for the Network ID and the last address is reserved for the Broadcast ID. The remaining addresses are available for hosts.
