Any computer which is connected to network and has unique ip address for the network.
Hosts
The maximum number of hosts per class B network is 65536.
Hosts
A hierarchical network

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.
The maximum number of hosts per class B network is 65536.
A network layer is not needed if both the hosts are in the same network. A data link layer can be used in such cases.

broadcast address
You can communicate only with hosts on your own physical network and with hosts on networks for which an explicit route exists, but not with hosts which are beyond the gateway and where no explicit route exists. Or, you can reach local machines but you can't reach Internet machines.
