When you want to represent several IPs, we use a combination of IP addresses and subnet masks. The subnet mask essentially acts as a bitmask that ensures the IP addresses in the range has certain bits same as the IP range’s address. Here is an example:

• IP Address: 192.168.1.0
• Subnet Mask: 255.255.255.0
• IP Range: 192.168.1.0/24

In this example, 24 is the number of bits set in the bitmask. This IP range has $2^8$ possible IPs.
