Azure DNS A record doesnt work

S H 45

So I have a domain that I purchased from Azure Domain services and added a DNS zone.

then I used A record to point the domain to IP address of my hosting provider. It worked.

Then I was trying to make email work , so to cleanup some record I deleted the DNS zone service and readded then added the A record again , but now I cant access the website as the domain is not really linked to IP and I get DNS_PROBE_FINISHED_NXDOMAIN in brwoser

when I ping my domain the ping cannot resolve the domain to ip

I waited two days , but nothing changed.

I give ttl 5 minutes but no diffrent.

Hi @S H,

Greetings! Sorry for the delay in response.

If you are getting "DNS_PROBE_FINISHED_NXDOMAIN" error, it means that the DNS resolver is unable to find any DNS records for the specified domain.

Please make sure that your DNS zone is correctly configured and DNS records for your domain are properly defined and ensure there are no typos or errors in the DNS records.

Verify that the A record is pointing to the correct IP address of your hosting provider.

Use below command to check the DNS records: nslookup yourdomain.com

Run below command to clear your local DNS cache to ensure you're not seeing cached results: ipconfig /flushdns

Please verify whether you have created any Private DNS zone, that might cause the issue.

There might be a chance that sometimes, firewall or antivirus settings may block certain domains or interfere with DNS resolution.

Please try to clear your browsing history and cookies by using Control + Shift + Delete, your browser automatically saves temporary internet files to help pages load faster. Clearing this cache will sometimes fix website issues.

Please back up all your personal files first, such as Favorites, to ensure you do not lose data.

Kindly let us know if the above helps or you need further assistance on this issue.

Thanks,

Sai Prasanna.

Thanks for the follow up, my issue still there , I have now added the two NS recrod entries to the ns records after the first 4 mandatory records that azure add them by default.

hopefully that will solve the issue otherwise I will have to transfer this domain to another registrar.

Update: Tried to link the subdomain to azure function but the validation failed although I added both record to the DNS records , I start thinking this domain is not really accessable, do I have to add any networking ? Currently I only have domain and DNS service added

Hi @S H,

Greetings,

As you mentioned above you have purchased a domain from azure, but Azure DNS does not currently support purchasing of domain names.

To purchase domains, you should use a third-party domain name registrar, who will typically charge a small annual fee.

For your reference: https://azure.microsoft.com/en-in/pricing/details/dns/#:~:text=No%2C%20Azure%20DNS%20does%20not%20currently%20support%20purchasing%20of%20domain%20names.%20To%20purchase%20domains%2C%20you%20should%20use%20a%20third%2Dparty%20domain%20name%20registrar%2C%20who%20will%20typically%20charge%20a%20small%20annual%20fee.

Where did you purchase domain like Go daddy, Namecheap etc...

As you mentioned above you have added a subdomain in azure function and it is not validating, please provide the error screen shot.

Have you tried to add the TXT record in azure DNS Zone? If not, please add the TXT record and then validate the domain in app services.

Kindly let us know if the above helps or you need further assistance on this issue.

Sorry, but that is maybe old documentation, Azure domain services allow you to purchase domain, they use GoDaddy as registrar in backend , but you purchase the domain from azure , and changing name servers is not possible, you can only add extra

Hi @S H,

Greetings,

We cannot change the Name Server records which is automatically created after deploying the DNS Zone.

After deploying the DNS Zone, from the Overview window, copy the values for all four name servers listed as Name server 1 to Name server 4 and set them aside in a text editor for later use.

The next step is to update the name server addresses for your domain name. Sign in to your account on your domain provider's website and find the tools to edit your domain settings. While each domain provider is different, look for Manage DNS, Domain settings, or something similar in your domain account.

Next update the 4 Name Server records which you have collected from Azure DNS Zone to Nameservers of your Domain and save the changes.

By default, you will get the NS and SOA records after deploying the DNS Zone, but you need to add other records like, A, CNAME and TXT records. For your reference: https://learn.microsoft.com/en-us/azure/static-web-apps/azure-dns-zone?source=recommendations

You can configure the custom domain in apps management page and create the DNS records and validate the domain ownership and complete the mapping.

Example DNS records:

For your reference: https://learn.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain?tabs=root%2Cazurecli#configure-a-custom-domain

Hi @S H,

Greetings!

You have tried all the troubleshooting steps and still facing the issue.

We understand that you want to transfer your domain to another registrar.

Please follow the below steps to achieve that:

Transferring of domain out of Azure (not a registrar) to another registrar is supported and you may currently do so via API and PowerShell. You will need to get an authorization code which you can take to the registrar of choice to proceed with transferring out of your domain.

Exceptions for transferring domain out:

You won’t be able to transfer your domain within 60 days of these events:

New domain registration

Transfer between different registrars

Change to registrant contact information

Special case for “.uk” domains:

For any “.uk” domains, you’ll need the new registrar’s IPS tag. Create a support case and provide the IPS tag. They will assist with updating the IPS tag on your domain to your new registrar and then you can complete the transfer out process with your new registrar.

The authorization code is a unique string of characters consisting of letters, numbers, and special characters (ie. ? ! ^) that is required to transfer a domain from one registrar to another.

Getting authorization code with transfer out API:

You can use the transfer out API:

PUT https://management.azure.com/subscriptions/<SUBSCRIPTION-ID>/resourceGroups/<RESOURCE-GROUP-NAME>/providers/Microsoft.DomainRegistration/domains/<DOMAIN-NAME>/transferout?api-version=2021-02-01

You may be able to run this API on Azure Resource Explorer. Fill out the necessary information in between the “<” and “>” from the above, then paste the API call to you Azure Resource Explorer. Highlight the entire line from “PUT” until “api-version=2021-02-01” and hit Ctrl+S to run the command.

Refer to the “authCode” value without the double quotes (“). This will be the authorization code you will need to provide the new domain registrar to transfer your domain out.

Getting authorization code with Powershell:

There currently is no first-class PowerShell support for domain transfer out. However, you can use the following call below to get your authorization code:

Invoke-AzRestMethod -Path "/subscriptions/<SUBSCRIPTION-ID>/resourceGroups/<RESOURCE-GROUP-NAME>/providers/Microsoft.DomainRegistration/domains/<DOMAIN-NAME>/transferout?api-version=2021-02-01" -Method PUT

Refer to the “authCode” value without the double quotes (“). This will be the authorization code you will need to provide the new domain registrar to transfer your domain out.

Using Cloud shell:

If you are having issues running the command in your local PowerShell, try using Cloud Shell on Azure Portal instead. You can access Cloud Shell on the top right navigation on Azure Portal. Once the Cloud Shell windows appear, check the top left corner of the window and make sure it says “PowerShell” and not “Bash”; otherwise, switch to “PowerShell”. Copy paste the command above and fill out the necessary information in between the “<” and “>”, then press enter.

Refer to the “authCode” value without the double quotes (“). This will be the authorization code you will need to provide the new domain registrar to transfer your domain out.

Kindly let us know if the above helps or you need further assistance on this issue.

We understand that you want to transfer your domain to another registrar.

And here is the disconnect, my issue is the domain is not resolving so I cannot use because no name server can recognize it, even the default 4 name servers cannot recognize recognize it. AS you see there I did nslookup but no results.

I placed a support ticket with microsoft but they are unable to solve it too , so since you gave me the way yo transfer my domain , I will transfer it to another registrar at least there I can use it. Thanks for trying to help me .

Hi,

First, this is happening because you deleted your Azure DNS Zone. Deleting the DNS Zone breaks DNS resolution. Creating a new zone didn't fix it, because the new zone wasn't placed on the same Azure DNS servers.

Second, I have a script that gives you full access to your GoDaddy Domain Control Center (DCC) which allows you to make any/all changes to your domain, similar to a regular GoDaddy customer. Unfortunately, my script relies on generateSsoRequest REST API which stopped working several months ago this year (2024). You can try the REST API yourself and see if they fixed it using the "Try it" button. If it is fixed I would be happy to post my script.

The manual way you can fix your domain is to repeatedly delete/re-create your Azure DNS Zone until it is placed on the correct DNS servers. To do this you need to first check what the "correct" DNS servers are:

Open whois.com in your web browser, enter your domain in the whois box in upper right corner, click whois button, scroll down to bottom of results and make note of the four name servers, similar to below:

Name Server: NS1-37.AZURE-DNS.COM

Name Server: NS2-37.AZURE-DNS.NET

Name Server: NS3-37.AZURE-DNS.ORG

Name Server: NS4-37.AZURE-DNS.INFO

From the above sample results, we see the correct name server is "37". This is our goal in this sample case--to have the DNS Zone land on 37. There are 47 (1-47). So once we know the correct number, we can carefully create the Zone, check which servers it landed on, delete it if it isn't on correct servers, create it again, etc.

Your number will be different.

NOTE: Azure DNS is not free. There is small cost for each zone per month, plus the number of queries (this isn't a concern in this case). I forget the minimum granularity it bills the zones at. For example, if it bills for minimum one hour and you have to create/delete a total of 100 times, then the total cost would be minimal. If the minimum is 1 month, then the cost could add up. Of course you could dispute and they would likely refund since it is same domain name.

Please let me know if the above isn't clear. If I knew your domain name I could tell you correct server.

Thanks.
