What is the range of usable IP addresses in dotted-quad form?

The range of usable IP addresses in dotted-quad form typically refers to the valid addresses available for hosts within the IPv4 addressing scheme. In a standard Class C network, the address range goes from 1 to 254, as the first address (0.x.x.x) is reserved for the network identifier and the last address (255.x.x.x) is reserved for the broadcast address.

This makes the range of usable IP addresses from 1 to 254, allowing for 254 unique host addresses that can be assigned to devices in that subnet. Therefore, when looking for valid host addresses, it is important to exclude the network and broadcast addresses, which is why the range starts at 1 and ends at 254.

This relates directly to how IP addresses are often structured for local networks, specifically in subnetting practices where addresses are divided into various classes, with Class C being one of the most common for smaller networks. Understanding this range is crucial for anyone working with networking and IP address assignments to ensure efficient and proper allocation of addresses within a network.
