    • This is to perform a IP to hostname lookup. We are using Google's DNS to perform the lookup. Since my lab is in private network, I am getting NXDOMAIN, but if you do a lookup of a public IP then you should get proper hostname value. Or you can also use your own DNS (if any) to perform hostname lookup
