Description:

The Python socket library has utilities to deal with the various IP address formats.

Here, we will use two of them: inet_aton() and inet_ntoa(). Let us create the

convert_ip4_address() function,where inet_aton() and inet_ntoa() will be used for

the IP address conversion.We will use two sample IP addresses, 127.0.0.1 and 192.168.0.1.

TEST:

IP Address: 127.0.0.1 => Packed:7f000001, Unpacked: 127.0.0.1
IP Address: 192.168.0.1 => Packed:c0a80001, Unpacked: 192.168.0.1
