Is it in class a in each network have 16777214 hosts?

In Class A networks, the maximum number of hosts is calculated as (2^{24} - 2), which equals 16,777,214 hosts. This formula accounts for the network and broadcast addresses, which cannot be assigned to hosts. Class A networks use the first octet for the network identifier, allowing for a large number of hosts within a single network. However, not every Class A network will have the maximum number of hosts; it depends on the specific subnetting used.
