Hosts Per Subnet

@Ginht: Do you have a reference indicating that the calculation for the number of hosts per subnet has changed? If we use a standard Class C (/24) network as an example, there are 256 addresses on the network, but only 254 hosts allowed. The first address is the network itself. The last address is the broadcast address. Those can't be used as host addresses. See https://tools.ietf.org/html/rfc1878 for more information. -- Dave Braunschweig (discuss • contribs) 15:12, 10 June 2019 (UTC)
