THE IP ADDRESS
Network address is more commonly known as IP address. It
is the numeric address of a computer connected to the network. It can be compared to the physical
address that we use for our homes which uniquely identifies it from the rest of
the homes in our neighborhood, town, city, province, country and the whole wide
world. IP address is
a set of numbers, called as “octets” or “dotted decimal” notation,
that identifies any network device.
IP VERSIONS
1.IPv4 (IP version 4) is
the standard version
2.IPv6 (IP version 6) is
the advanced version
IPv4 – Internet Protocol version 4
IPv4 addresses are canonically
represented in dotted-decimal notation,
which consists of four decimal numbers, each ranging from 0 to 255, separated
by dots, e.g., 172.16.254.1. Each part represents a group of 8 bits (octet) of
the address.
