CIDR Notation
Classless Inter-Domain Routing (CIDR) notation represents IP addresses and their network masks. /24 means the first 24 bits are the network portion.
Common Subnets
- /24 = 255.255.255.0 (256 addresses, 254 usable)
- /16 = 255.255.0.0 (65,536 addresses)
- /8 = 255.0.0.0 (16,777,216 addresses)
