Configuring DNS records for Azure Websites - azure-web-app-service

The instructions on Azure regarding configuring DNS records for Web sites are easily misinterpreted, and people often has issues with configuring the DNS records required, or instructing others (IT) how to make the required DNS changes.
This post is now obsolete, the azure documentation is great these days.

Multiple DNS records are required to assign a domain to a website in Azure.
For each domain and sub domain a pair of DNS records is required. The A record is required to point the domain at Azure, and the CNAME record is required as this validates the Azure website you are associating the domain to.
For a normal website, you are likely to need 4 records:
2x A Records
2x CNAME Record
E.g.
Type Name Value
A # 123.123.123.123
A www 123.123.123.123
CNAME awverify awverify.foobar.azurewebsites.net.
CNAME awverify.www awverify.foobar.azurewebsites.net.
With the IP Address being your IP address associated to your Azure website,
and 'foobar' being your Websites name.
Here we have two pairs of records, because one is for the domain, and one is for the 'www' subdomain. Please note a 'awverify' record is required for every sub-domain and the follows the format of awverify.subdomainname.
I have built a small tool that outputs this information, so that it can easily be copied and pasted, for when you need to share this information with IT, other people, etc!

While working with App Service on Azure and godaddy as domain provider, I found out that we need below record to make it work.
ARecord ( with IP Address )
CName ( record for main site address
) and other CNAME ( for www )
TXT Record ( txt record for main site
address)

Why Azure DNS Zone create afdverify subdomain automatically and how to stop?

I create a CNAME record in DNS ZONE (e.g: site1.example.com). And then, afdverify.site1.example.com and site1.example.com will be created.
I just want to create site1.example.com only.
• #Kyakya, from your query and the screenshot, I can understand that you are trying to create a CNAME record for the ‘site1.example.com’ URL. But when creating a CNAME DNS record in a DNS zone, you will have to mention its alias FQDN URL, i.e., that original URL which you are trying to mask or associate with by creating this CNAME record. Thus, I can understand from the screenshot that you are trying to create a CNANE record for the Azure front door URL in DNS zone in Azure.
As a result, when you create a CNAME record with a custom domain name for an already hosted URL, you need to ensure that the original hosted URL is reachable and available as the CNAME record created will only redirect the DNS requests to the original hosted URL only.
• Since, in your case, you don’t want to create a subdomain regarding ‘site1.example.com’ in your DNS zone, i.e., ‘afdverify.site1.example.com’ so in that scenario, you will have to create an ‘A’ host record for the ‘site1.example.com’ in your public DNS server where your basic custom domain ‘example.com’ is registered. Once done, then create a CNAME record for the inbuilt Azure generated FQDN of that resource in your public DNS zone in that DNS server with ‘site1.example.com’ that you want.
And if you don’t want that too, then you will have to verify your custom domain in Azure, and then create resources in Azure based on the records created in DNS zone provisioned.

Azure app service wrong redirection for new domain

I acquired a new domain name in Azure (let's say mynewdomain.net), assigned it to my app service, bought a certificate also in Azure and made the bindings. Apparently both the domain and certificate are properly configured.
When I invoke the domain in any browser like https://mynewdomain.net, I get redirected to https://mynewdomain.net/mynewdomain.net, and of course fails.
The problem must be very simple, but I have no clue! Can anyone point me in the right direction here?
Thanks!
To create a CNAME mapping for the www subdomain, create two records: CNAME and TXT records.
After you add the CNAME and TXT records, the DNS records page looks like the following example:
To map an A record, you need the app's external IP address. You can find this IP address on the app's Custom Domains page in the Azure portal.
After the records are added, the DNS records page looks like the following example:
For more details, you could refer to this article about mapping an existing custom DNS name to Azure App Service.

Adding MX record for Network Solutions email to Azure App Domain

I need to add an MX record into the app domain name purchased thru Azure portal.
The default form to add a record set adds the .domainname after the mx record name.
The problem is that Network solutions says the MX record name must be mx1.netsolmail.net. (So in the portal it becomes mx1.netsolmail.net.domainname.com which is not what I need)
How can I add a record set in my DNS zone for that domain that doesn't end in the domain name?
Per the answer below I changed the settings to the following
When you purchase a domain in the app service domain page, you actually have a new domain provider because App Service Domains use GoDaddy for domain registration and Azure DNS to host the domains.
If I am understanding it correctly, you would like to have an email delivered on your app domain name through Network Solutions but keep your domain through Azure. If so, you could refer to this Mailbox Setup and configuration to change/edit your MX and CNAME records in the Azure DNS zone.
Try to change the MX record to inbound.[domain name].netsolmail.net if your domain name was janesbagels.com, your Mail Server record would look like inbound.janesbagels.com.netsolmail.net. Also, you could change the other two CNAME records mail and SMTP.

Root domain in Azure FrontDoor configuration

I am trying to set up the routing for the Apex/root domain of my website(myrootdomain.eu) in Azure FrontDoor.
Reference :https://learn.microsoft.com/en-us/azure/frontdoor/front-door-how-to-onboard-apex-domain
Crated the Alias record with #.myrootdomain.eu in Azure DNS against the Azure resource as FrontDoor. A CNAME was created like this : afdverify.myrootdomain.eu
When i try adding the custom domain(myrootdomain.eu) into the frontend host of FrontDoor, it is giving the error CNAME record is not found. What additional step is required here .
Is there any setting or mapping to be done in my DNS 123domain or frontdoor for this domain : afdverify.myrootdomain.eu
What should be the mapping in domain provider (123domain in my case) for the naked domain(myrootdomain.eu) ?
Could not find any thing about that in the reference doc.
If you have hosted your domain in Azure DNS, (that is to edit the NS records and replace the NS records with the Azure DNS name servers in the registrar's DNS management page), you do not need to map in your original domain provider. It takes just a few seconds on my side to wait for the DNS taking place for the Apex/root domain in Azure Front Door.
After creating an alias record for zone apex, it creates a zone apex record pointing to your Front Door resource and also a CNAME record mapping 'afdverify' (example - afdverify.contosonews.com) to afdverify.<name>.azurefd.net.
If you have finished the above steps correctly, it usually takes some time for DNS propagation, you could check it via whatsmydns or viewdns. As the comment said, you can check if the CNAME is effective or not using nslookup or google dig tool.

WWW domain on azure

I am trying to configure a www domain on azure. I want to have website under this domain. My domain is "legia.fitness". I have created the DNS zone as follows:
On this picture you see 4 DNS servers. I have delegated my domain that I bought at home.pl to those servers:
And this doesn't work. When I try to browse legia.fitness I get "ERR_NAME_NOT_RESOLVED" error. What am I doing wrong?
Your Azure DNS zone does not have any A or CNAME records for www or # so the name cannot be resolved to an IP address.
Add a new A record with the label # set to the IP address of your Azure website, and another A record with the label www also set to the same IP address.
Alternatively, create CNAME records (both # and www) and set them to your Azure Website's name (e.g. yourwebsite.azurewebsites.net). CNAME records are aliases of existing A or CNAME records, but are slower to resolve which is why I prefer A records.
You haven't directed the domain anywhere yet.
You have a DNS zone that works. I can see the SOA records on Dig web interface.
Now you have to add CNAME/A records to the DNS zone to direct the traffic to where you want it.
