Internet Architecture
Two computers, anywhere in the world, following certain hardware,
software, protocol specifications, can communicate, reliably even when not
directly connected.
LANs are no longer scalable beyond a certain number of stations or
geographic separation.

Hosts for Classes of IP Addresses
Class A (24 bits for hosts) 224 - 2* = 16,777,214 maximum hosts
Class B (16 bits for hosts) 216 - 2* = 65,534 maximum hosts
Class C (8 bits for hosts) 28 - 2* = 254 maximum hosts
* Subtracting the network and broadcast reserved address
