Let’s say, IP of my PC=192.168.1.5
IP of my local DNS=10.10.10.10
IP of resolver1 = 1.1.1.1

(don’t worry about routing) assuming port 53 open everywhere.

when we use from myPC# dig @resolver1 test.com ==> whether the local DNS of my PC is being used? or is it the IP address of my PC used as the source IP?

Thank you man! Very useful article !

Another trick: it’s possible to use a specific DNS-RESOLVER IP-address, instead those from the system ( /etc/resolv.conf ).

Below, I queried to the PUBLIC RESOLVER from Google (8.8.8.8):

# dig @8.8.8.8 http://www.google.com. +short
189.86.41.103
189.86.41.109
189.86.41.84
189.86.41.118
189.86.41.93
189.86.41.98
189.86.41.104
189.86.41.108
189.86.41.99
189.86.41.119
189.86.41.113
189.86.41.123
189.86.41.88
189.86.41.89
189.86.41.94
189.86.41.114
