Protocol version 4/IPv4 address IPv4 uses 32-bit addresses, so
if you view the address in its binary format, it has 32
characters, as the following example shows: 1. The unique
identity of the computer, which is the host ID. 2. The subnet on
which the computer resides, which is the network ID. 3. This
enables a networked computer to communicate with other networked
computers in a routed environment. Internet Protocol address
version 4 /IPv4 classes The Internet Assigned Numbers Authority
(IANA) organizes IPv4 addresses into classes. The number of
hosts that a network has determines the class of addresses that
is required. IANA has named the IPv4 address classes from Class
A through Class E. Class A = Any IP address in which the first
octet has a value between 1 and 127 is a part of a Class A
network. there are only 126 available Class A network, each with
up to 16,777,214 hosts. Because Class A networks are very large,
they are allocated to very l
