For those who are not familiar and want to know what is IPv4 addressing, it is the 4th version of connection-less Internet Protocol. It is by far the most used and popular form of TCP/IP Protocol Suite (What is IPv4 addressing).

What is the IPv4 address

An IP address from version 4 of Internet Protocol is an identification number that is required by a machine or computer that uses the internet(What is IPv4 addressing). 

IPv4 in networking?

IPv4 in networking is wherein a network, IPs of different devices are used to communicate with each other. 

How does IPv4 work? 
An IPv4 is a 32-bits size address space (four bytes) or 232 containing 4,294,967,296 IPv4 addresses. The IP address has two parts, a host address, and a network address. The host address is the identifier of a computer on a local area network, whereas the network address is the identifier of a specific network on which the computer is connected.
IPv6 is more compatible with mobile networks than IPv4
Classes of IP addresses?

The IP address is divided into five parts and accordingly, are allocated to companies or corporations depending on their usage or requirement:

Class A – Has 127 networks and supports 16 million hosts on each network

Class B – Has 16,000 networks and supports 65,000 hosts on each on each network

Class C – Has 2 million networks and supports 254 hosts on each network 

Class D – It supports one host to many hosts and also many hosts to many hosts in a group

Class E – It supports private usage like research work etc.

Why are companies hesitant in deciding between IPv4 and IPv6?

Mask in IPv4 addressing?

In IPv4 addressing, a mask is a divider that separates the IP address into two parts the network addresses and host addresses.
A mask or subnet mask is a number 32 bit long and helps control or mask the network side of IP addresses(What is IPv4 addressing).

Classful and classless IP addressing:
In Classful addressing (Class A, B, and C), there are three parts in an IP address – Host, Network and Subnet and the routing protocol does not support mask.Whereas, in Classless addressing, there are only two parts in an IP address – Subnet and Host and the routing protocol supports mask.

Classful addressing was used from 1981 till 1993, after which classless addressing was introduced.
