In a /24 CIDR, how many bits are used for the network portion?

Explanation:
CIDR notation shows how many leftmost bits in an IPv4 address form the network prefix. A /24 means the first 24 bits are the network portion, leaving 8 bits for hosts. That corresponds to the subnet mask 255.255.255.0, where the network spans the first three octets and the last octet identifies individual hosts. So the network portion uses 24 bits.
