These are the values of bits in an octet: 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 If a mask is 255.255.255.128 , that last octet has the first bit turned "on." in binary = in decimal. CIDR Notation Instead of writing 255.255.255.0 Slash Notation means the first 24 bits are "on" (255.255.255.0). means the first 25 bits are "on" (255.255.255.128).
