Cisco router Configuration routing

[souravpathak]

Pls provide the CIL commands to configure DNS for the Network. 

Cisco 1921 router. In the Picture1941 work as 1921 Router. 

I cant able to access the network with DNS setting 8.8.8.8. 

1941 will be replaced with 1921 in actual network

Hello @souravpathak,

You want to configure DNS IP server on Cisco router ?

ip name-server 8.8.8.8

[MHM Cisco World]

This is packet-tracer there is no connect to real network so there is no

dns server 8.8.8.8

He need to make router as dns server and make host ask router to resolve IP.

In router he need to add

hostname-IP

This host is server cisco.com

My Cisco 1921 K9 router unable to connect with internet through ISP router. I got a mess in web browser "DNS_PROBE_FINISHED_NO_INTERNET" .

When I connect a external router in between the ISP and Cisco 1921 it work.

I have done this configuration
