A standard /24 IPv4 network contains 256 total IP addresses, of which exactly 254 are usable for host interfaces. The first address (.0) is reserved as the network identifier, and the final address (.255) is reserved as the directed broadcast address, leaving addresses .1 through .254 for devices.
Total Addresses = 2^(32 − 24) = 256; Usable Hosts = 256 − 2 = 254
IPv4 CIDR & Subnet Calculator Engine
Calculate network boundaries, usable IP ranges, broadcast addresses, wildcard masks, and binary bit allocations from an IP and prefix. Compliant with RFC 4632 (CIDR), RFC 3021 (/31 point-to-point links), and RFC 1918 private networking.

Binary Representation & Bit Boundary

Frequently asked
Direct answers for search, answer engines, and generative crawlers.
No. Standard IP routing stacks drop packets addressed to the network ID or broadcast ID as invalid destination unicast addresses. Only RFC 3021 /31 point-to-point subnets waive this rule.
