Suggestions: If 2 ​ephemeral node is resolving out of 4 mean dns is resolving ip address.

​

Did ​you run the dig command to check right name server?

​

Try below command.​ Example:

dig example.com +short +identify
dig foo.example.com +all

​Let's us know the issue.

Thanks​

Hi Samir,

 

I meant i have 4 name servers configured. But ephimeral node still doesn't populate.

 

Out of 4 two name servers are reachable from device and 2 are not reachable. Ideally it should populate the ephimeral node but issue here is it doesn't.

 

Thanks
