Taks - DNS TroubleShooting

Hi Guys,

I’m very new on this platform and all this technologies. First task I have assigned is - DNS TroubleShooting, really not idea where to start, so would be really helpful if somebody can give me some guide about where to find the solution of this problem or where can learn more about this specific topic.

you have to move into /etc/resolve.conf file by cat command. You can see that output on terminal. By using Vi editor help add google universal DNS in that nameserver 8.8.8.8 after that it is resolved. Dont restart network service otherwise it will reset again. so as per question, task is temporary basis.

Thank you! Very useful

@Inderpreet hello i did add open sudo vi /etc/resolv.conf and added google ipv6 dns name servers
nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844
and saved the /etc/resolv.conf and then i pinged for ipv4 8.8.8.8 and got response for the ping, however the task says failed, with reason no valid google public dns found on app server 2

@Inderpreet pls specify in the task whether we have to add ipv4 dns nameserver or ipv6 dns nameserver, even if we are adding ipv6 dns servers and when i did $ping 8.8.8.8 it did give response correctly.but the task result says failed.
