CIDR Cheat Sheet
Classless Inter-Domain Routing (CIDR) notation is a method for specifying IP addresses and their associated network masks. It simplifies the address format by using a suffix (e.g., /24) to indicate how many bits are used for the network portion of the address, with the remaining bits reserved for host addresses. Below is a table summarizing…
