We have followed this instruction to use cloud DNS to set up host name of our GCE instance, which external IP is static. But we still cannot look up the domain name of our GCE instance from the internet after waiting several days. Is there anything that we miss when we setup cloud DNS??
Are you using Cloud DNS as the Name Server too?
If yes, please follow the steps here to update your domain registrar's name server setting
https://cloud.google.com/dns/update-name-servers
Is the Cloud DNS name server reflected in your domain registrar's name server setting? What is the dig response for your domain search ?
To set up a domain name on GCE via cloud dns, you need to set up a Cloud DNS managed zone and then setting up Address (A) and Canonical Name (CNAME) records for the domain. Please see below procedure on how to set up Cloud DNS managed zone, A record and CNAME records:
Create a managed public zone [1].
A managed zone is a container for DNS records of the same DNS name suffix. A managed zone has a set of name servers that accept and responds to queries. Create a new managed public zone:
[1] https://cloud.google.com/dns/docs/quickstart#create_a_new_record
Create a new record for A record [2].
[2] https://cloud.google.com/dns/docs/quickstart#create_a_cname_record
Create a CNAME record [3].
The record update will take some time to propagate depending on the time-to-live (TTL) values in your zone. You can verify that the DNS records are working by visiting the domain name and confirming that the domain resolves to your IP address.

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.
after changing name servers in my registered domain (in namecheap) which has the name for example "contoso.net" to name servers, which matches the four nameservers in my Azure DNS zone (ex: ns1-08.azure-dns.com) I could not access my website as usual , and I receive the error message, which referes to the this problem with name servers (DNS_PROBE_FINISHED_NXDOMAIN).
so, when I reset again the default name server to "namecheap web hosting DNS", then I can again access the website.
can anyone help? thanks!
When you change the name server for that domain to Azure provider name server, actually you have delegated that domain to Azure DNS name servers and you could edit your DNS records in the Azure DNS zone.
In this case, you need to add A or CNAME records mapping to your website's hostname or IP address in your original domain provider, then you will access websites again. Usually, it takes about a few minutes or hours for the DNS propagation. If you still could not access the websites after verifying the DNS update, please clear the cache or type ipconfig/flushdns on the windows command prompt.

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.
Is there a way to point an Azure NIC to the records one created in an Azure DNS zone?
At present Azure DNS doesn't support private DNS zones, i.e. those only available to your vnet. Also, the DNS servers specified in the "Add DNS server" box needs to be a recursive resolver, Azure DNS is an Authoritative DNS service, i.e. it will only serve answers for the zones it hosts.
We can't add Azure DNS zone to NIC custom DNS. The custom DNS required IP address, we can add the DNS server IP address to it.
For example, we can add 8.8.8.8 to it, also we can add local DNS server IP address to it(need VPN). Or create a Azure windows VM and install DNS role on it, and add this VM ip address to it.
If you want to use Azure DNS zone to manage your records, we can map your own domain name to DNS zone, and add name servers to your domain name(add this by domain name registrar manage webpage).
The following image shows an example DNS query about Azure DNS zone:
If you want to add record to DNS zone, and you want to map your 3rd party domain name map to Azure DNS zone, we can follow those steps in that answer.
Note:
Keep in mind Azure DNS is not the domain registrar, we should buy domain name from domain registrar(like godaddy, register.com).
Update:
If you just want to use domain name in your virtual network, there is no need to buy a domain, we can use AAD DS in our virtual network. Or we can deploy a VM and install DC on it, work as on-prem.
By the way, in the same virtual network, we can ping VM's name by default.
I have searched the net and cannot find an answer to this question. I have created a .ga domain with freenom.com.
I created two dns records in freenom.com. The A record maps to the public ip of the virtual machine and the cname record maps to the azure domain name - xxxxx.eastasia.cloudapp.azure.com. I set the ttl in both records to be 3600.
I give some hours for the dns records to propagate and try to do an nslookup on my .ga domain but it does not seem to exist. I try pinging, browsing the url but it seems that my domain does not exist.
Any help on this issue would be greatly appreciated.
For VM, you need to specify it on the Cloud Service level - did you do everything according to the official guidance?
If you use non-classic VM (ARM), then the situation is a little more complicated - you may go with that approach or with the Azure DNS service.
Your VM Name looks like : "name.cloudapp.azure.com". By default public IP address is created not static address that means you can't use DNS record on it.
If you want to use different domain name like "xxxxtest.com" then you have 2 options:
Use 'CNAME' DNS record
Use reserved IP record on Azure and 'A' DNS record
