Classes for data validation

This c++ code checks whether the given ipv4 is valid or not.

The IPv4 Validator CLI application provides a convenient way to validate IPv4 addresses from your command line. It helps you ensure that an IPv4 address is correctly formatted and falls within the valid range of IP addresses.

The primary objective of an IPv4 validator project is to verify that an IPv4 address is valid and correctly formatted. To determine whether the supplied address is a valid IPv4 address and to determine the class to which it belongs, it performs a number of checks and validations.
