Subnetting and IPs - JuliaLightCNCS/Net-150 GitHub Wiki

Max 255 and minimum is 0

32 bites

If the ip address is 255.0.0.0, the number in the first octets will add up to 255.

For 255 this would be how it would look in binary. y = turned on

y = 128 y = 64 y = 32 y = 16 y = 8 y = 4 y = 2 y = 1

CIDR is after the ip address. It tells you how many bits are turned on and what the subnetting is going to be. If the last octet isn't reached the number will be 0

Ex: 192.10.8.7/16
