Hi,

I have created Azure App service Domain and delegated to public DNS zone, everything was working fine, then I have deleted the DNS zone, and created again from inside my Azure App Service Domain windows "Manage DNS records" option.

Now my records created in the DNS not propagating to public /internet, Ican't open my website from internet, because DNS not resolving the ip address correctly, I can browse my website with ip-address without issues.

My App service domain mapped with NS (name servers) other than the NS (name servers) showing in azure DNS zone.

when I do DNS lookup using the NS name servers mapped in my DNS zone, the resolution is working fine, but when I try it without specifying any name server the name resolution failed.

and as a result I can't resolve my DNS records publicly.

I don't see any option in Azure to manage and update name servers in App service domain,

as a workaround, I have added the name servers that is showing in App service domain to the DNS @ record, but resolution this doesn't help..

Any advise how to fix..

Thank you...

    Hi Mohamd Abdalla Elashry,

    Good day!

    Welcome to the Q&A Platform for Microsoft! We appreciate you posing your query here.

    NOTE: Check the expiration date for the domain from the below document, which tells us whether the domain is legitimate or not. If it has not expired, it should work.

    Refer: https://learn.microsoft.com/en-us/azure/app-service/manage-custom-dns-buy-domain#renew-the-domain

    Updated Note: That updating the name server in Azure is not supported.

    And here's one Approach you can try with DNS delegation

    Refer: https://learn.microsoft.com/en-us/azure/dns/dns-domain-delegation

    Refer: https://learn.microsoft.com/en-us/azure/dns/dns-faq#can-i-co-host-a-domain-by-using-azure-dns-and-another-dns-provider-
