Python DNS server to redirect all the requests to a IP

redirecter.py

import socket

#From https://stackoverflow.com/questions/41723507/create-a-dns-server-and-redirect-all-request-to-my-site
#Translated and made it work with newer python

#Run as admin: sudo python3 redirecter.py
#You can test the server with the host command in linux: host google.com 127.0.0.1
