Find Domain Name From DNS Pointer (PTR) Records Using IP Address

Write a function that takes an IP address and returns the domain name using PTR DNS records.

Example

get_domain("8.8.8.8") ➞ "dns.google"

get_domain("8.8.4.4") ➞ "dns.google"

Notes

• You may want to import socket.
• Don't cheat and just print the domain name, you need to make a real DNS request.
• Return as a string.
