Question : Display DNS

Hi all,
I would like to see if DNS is set on our router but I don't know what command I use. Could you please show me which one to do it?
Thank you

Answer : Display DNS

if you're looking to see if it's set in a DHCP pool, try:

show config | include dns

If you're looking to see if it's set for the IOS, use:

show config | include name-server
