CIDR notation is a compact representation of an IP address and its associated routing prefix. 192.168.100.14/24 represents the IPv4 address 192.168.100.14 and its associated routing prefix 192.168.100.0, or equivalently, its subnet mask 255.255.255.0, which has 24 leading 1-bits. The number of addresses of a subnet may be calculated as 2address length − prefix length, where Read more…
