About CIDR Notation
CIDR (Classless Inter-Domain Routing) notation is a compact method for specifying IP addresses and their associated routing prefix. It's a way to allocate IP addresses and route IP packets.
CIDR Format
A CIDR address looks like a normal IP address, followed by a slash and a number. For example: 192.168.1.0/24
The number after the slash represents the number of bits in the network prefix. In IPv4, this can range from 0 to 32.
Common CIDR Blocks
| CIDR | Subnet Mask | Number of Addresses |
|---|---|---|
| /32 | 255.255.255.255 | 1 |
| /24 | 255.255.255.0 | 256 |
| /16 | 255.255.0.0 | 65,536 |
| /8 | 255.0.0.0 | 16,777,216 |
