Azure DNS CNAME records - azure

I am trying to configure Auth0 custom domains with my azure web application. It is asking for a CNAME Record to be set.
I set this up in azure with a provided dns name, and set up the values as such:
but the verify button still does not work. i heard you may need to wait a few days for it to settle, but i waited all weekend with no luck. i saw in this post i may want to remove the NS and SOA types?
Wildcard and Naked CNAME records in Azure DNS
how can i verify this domain

As far as I know, you can not use the domain *.cloudapp.azure.com as the custom domain for your Auth0 as it is owned by Azure. You need to purchase a domain from the domain provider like Godaddy to configure your custom domain. Then you could validate that domain ownership.
You can't use Azure DNS to buy a domain name. Azure DNS is a hosting service for DNS domains that provides name resolution by using Microsoft Azure infrastructure. It's not necessary. You can selectly host your domain in Azure DNS.

Azure DNS Zone - unable to find CDN endpoint in list when adding record

I've setup a static site with Azure WebsiteCDN with custom domain, which works correctly for www.mysite.com
Now I'm trying to create an alias record set in DNS Zones (to point to apex domain) however the list is always empty:
Any ideas why it doesn't show up?
Mapping your apex or root domain to your CDN endpoint basically requires CNAME flattening or DNS chasing. There are other DNS providers as well that support CNAME flattening or DNS chasing, however, Azure CDN recommends using Azure DNS for its customers for hosting their domains.
Refer : https://learn.microsoft.com/en-us/azure/cdn/onboard-apex-domain
If you are using a different provider than Azure DNS, then you would need to contact the DNS provider and check if they support CNAME flattening or if there is any way to achieve this on their end.
If it is not supported with your DNS provider, then you could delegate your domain to Azure DNS and manage your DNS records in Azure DNS and here you will be able to create an Alias record which will help you onboard your apex domain to Azure CDN.
Please refer : https://learn.microsoft.com/en-us/azure/dns/dns-domain-delegation
https://learn.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns
While selecting the CDN resource in alias record set, make sure you have selected the subscription in which the CDN endpoint is deployed.
Important Note : Pointing a zone apex to CDN endpoints for Azure CDN from Akamai is currently not supported.

Azure Front Door and DNS Configuration

I'm having issue configuring my DNS to make all traffic routed from the root domain (no www) to the Azure front door. The below is what I have done so far:
Create the front door (frontend/backend/routing)
On-Board my custom domain (let's say hello.com) on front door
Now as per Microsoft guide I have to add a CNAME record to the DNS hosting provider (domain.com) to route the traffic to front door. But I have been told by domain.com that I cannot have A record and CNAME record named #
So I've found this solution https://learn.microsoft.com/en-gb/azure/frontdoor/front-door-how-to-onboard-apex-domain
Then I have created a DNS Zone on my Azure environment named "hello.com" and followed the guide.
Still I cannot see the traffic going through the front door.
Is that because I have 2 DNS servers? (one hosted on domain.com and another one on Azure)?
Can It be propagation time ?
Also how does azure know that I'm the owner of hello.com domain ?
As the linking document, to onboard a root or apex domain on your Front Door, you could use alias records in Azure DNS.
There are other DNS providers as well that support CNAME flattening or
DNS chasing, however, Azure Front Door recommends using Azure DNS for
its customers for hosting their domains.
If you select to use Azure DNS to host DNS domains, first you need to create an Azure DNS zone (hello.com) in Azure and delegate the domain to Azure DNS via changing the name server records for the domain in your original DNS registrar. You can verify the delegation by using a tool such as nslookup to query the Start of Authority (SOA) record for your zone. It can take up to 72 hours to propagate worldwide, although it typically takes a few hours.
Then, you can add an alias record for the zone apex in the DNS configuration for the domain to be onboarded. After this, you can add the apex domain name in the custom host name field on the Front Door designer tab.
To access your backend web app with the custom domain, ensure that you have created appropriate routing rules for your apex domain or added the domain to existing routing rules. Or, you may enable HTTPS on your custom domain.

Azure DNS for country Domain

I want to use my country domain which is mydomain.id after setting up in my azure DNS and domain provider, I still cannot validate my domain in App Service. I already double-check everything and I think my settings are already correct. Now I wonder can we use the Country domain in my azure DNS because I'm afraid if it's that the problem.
First of all, I assume you are using a public domain. As Martheen's comments mentioned that you just need to create DNS records to map your app service IP or hostname like webapp.azurewebsites.net in your DNS provider so that you can add custom domains in your App Service. This is tutorial.
Azure DNS is a hosting service for DNS domains that provides name resolution by using Microsoft Azure infrastructure. By hosting your domains in Azure, you can manage your DNS records by using the same credentials, APIs, tools, and billing as your other Azure services. You have the option to host your records on Azure DNS.
After adding the DNS records, you can use the local tool nslookup or websites https://dnschecker.org/ to check the DNS propagation. It can take up to 72 hours to propagate worldwide, although it typically takes a few hours.

How to change the DNS Zone nameserver in Azure?

How do I change the nameserver in a Microsoft Azure DNS Zone to be something else? I'd like to use Cloudflare for my nameservers instead of the default Azure ones.
As far as I know, you can not change Microsoft azure DNS name server. Azure DNS is a hosting service for DNS domains that provides name resolution by using Microsoft Azure infrastructure. But Azure DNS supports co-hosting domains with other DNS services.
To set up co-hosting, modify the NS records for the domain to point to the name servers of both providers. Read here.
For example, you can add name servers from Cloudflare in the additional name servers in the NS record on the Azure portal.
The Name Server (NS) update are done on the domain registrar side. In 'Azure DNS', Microsoft just manages the domain they are not the registrar.
If you want Cloud Flare to manage your domain the NS record needs to be change on the domain registrar side.
If you bought an Azure App Service Domain, you get a DNS Zone (mine didn't work properly, and that's how I got to my solution). You also get a second resource from the domain itself (the App Service Domain resource). If you there click on the tab Advanced Management portal you will be redirected to a different site. From there you can go to the DNS tab at the top, select Manage Zones and fill in the domain you want to control.
From there, scroll down, and you'll see something like this.
As you can see, there are two nameservers. Those nameservers point to Azures DNS system. But here, you can actually change the nameservers.

Delegate Subdomain to Azure via CNAME

the company I’m working for provided me a subdomain. test.mycomp.com . I want to add it to my azure web app via custom domain.
The azure system recommends a CNAME delegation and provided me the information to enter web-zeudz-staging.azurewebsites.net in the dns management as CNAME.
After doing so and verifiying via DNS Lookup, Azure always gives me „Domain Ownership Error“. What can I do to make this work?
Is your DNS provider also a CDN provider, for example cloudflare? If so, turn off the CDN/proxy function so it's a DNS only record and try again.
If you don't have any control over the CDN function you can use txt record validation.
Create your TXT record awverify.subdomain.test.mycomp.com with value web-zeudz-staging.azurewebsites.net and validate again. It should succeed.
There's also a CNAME awverify method but you need CDN disabled for that too.
I find it strange that your company doesn't have the option to enable/disabled CDN for any given DNS entry though.
