Ubuntu – Get current DNS server on 16.04-server

16.04dnsserver

Is there a simple command to find out which DNS server I'm using right now? Preferably without resorting to tcpdump or parsing log files?

I found a lot of stuff about nm-cli and other nm-tools but that doesn't apply to a server…

Best Answer

nslookup can be used to get the DNS server that is being used.

Example:

$ nslookup www.google.com
Server:     10.0.0.1     <--This is the DNS server address.
Address:    10.0.0.1#53

Non-authoritative answer:
Name:   www.google.com
Address: 216.58.217.36

Hope this helps!
