What does /24 mean in an IP address?

The /24 tells you how many bits at the front of the IP address are the network portion. /24 = first 24 bits are the network, remaining 8 bits are the host — giving 256 total addresses (254 usable, since the first is the network address and the last is broadcast). Example: 192.168.1.0/24 covers 192.168.1.0 through 192.168.1.255.
