WHAT IS A NETWORK OR IP ADDRESS?
Network Address
Network Address or also known as IP Address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. IP addresses allow the location of literally billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other devices.Network address is a set of numbers, called as "octets" or "dotted decimal" notation, that identifies any network device. ‘IP’ stands for ‘Internet Protocol’.
There are two versions of IP that currently coexist in the global Internet:
a. IP version 4 (IPv4) - IP version 4, is currently the standard version.
b. IP version 6 (IPv6) - IP version 6, is the advanced version.
IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long.
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. Each represents a group of 8 bits (octet) of the address.
IPv4: CLASSES OF IP ADDRESS
Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses from the first three classes (A, B and C) can be used for host addresses.
CLASS A - 1 to 126
CLASS B - 128 to 191
CLASS C - 192 to 223
CLASS D - 224 to 239
CLASS E - 240 to 255
127 - is a loop back function of the network
Class D - is for multicast
Class E - reserved for future or experimental purposes
Typical home networks use IP addresses that start with 192.168.
IP address such as:
192.168.1.1 or 192.168.2.1
