How many hosts in a /24 network?
A /24 network supports 254 usable hosts out of 256 total IP addresses. The usable range excludes the network address and broadcast address.
What subnet mask does /24 use?
A /24 subnet uses the mask 255.255.255.0 (wildcard mask 0.0.0.255). This means the first 24 bits identify the network and the remaining 8 bits identify hosts.
