    1. Support reverse DNS for Azure Container Instance (ACI)

      For my project I'm setting up an Azure Container Instance with a public IP address and FDQN. The docker image used (OWASP ZAP), requires a reverse DNS.

      At this moment a public IP address is not visible in the Azure CLI networking, and this a reverse FDQN cannot be setup and results in the following error;

      PublicIp is trying to use does not belong to subscription yyyyyy. One of the following conditions need to be met to establish ownership: 1) ReverseFqdn matches fqdn of any public ip resource under the subscription; 2) ReverseFqdn resolves to thefqdn (through CName records chain)…

    2. SQL Managed Instances VNET DNS Queries are not clear and impact Windows VMs on the same VNET

      There is no clarity on how DNS is resolved under a SQL managed instance VNET and the consequential impact on Windows VMs hosted in the same VNET

    3. Provide traffic manager regions in Africa/South Africa

      Hi,

      You currently have good coverage for external external traffic manager endpoints everywhere except none in Africa. This will result in poor performance for Africa clients even if we put servers all over Africa.

      Do you plan to extend Azure coverage to Africa/South Africa?

    4. Performance based load balancing should consider application load as an input

      Akamai offers ability to load balance traffic based on the current load of the endpoint. The endpoints return load data via GET or POST to the akamai api. This basically enables customers to get best of both the world's, be able to route traffic to the least latent node and fail over to next latent node if it gets overloaded.

      It can be argued that the node should take itself offline via health probes when it is overloaded, but that's not ideal as it would cause massive traffic swings instead of smoothening out the requests.

    5. Support Azure Traffic Manager endpoints that are nested and external to allow us to use alias records

      We have an Apex domain that needs to point to Traffic Manager. We use Traffic Manager nested profiles.
      We want to use alias records to point to our DNS alias record to Traffic manager. This requires using external endpoints in traffic manager.
      Problem is that we use nested profiles. It is not possible to create nested external endpoints in traffic manager.

      Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature list and also gives us insight into the potential impact of implementing the suggested feature

    6. API to retrieve the max number of DNS zones currently configured in each sub

      A support ticket can increase the max number of DNS zones in a subscription (and correspondingly reduce the max number of records in zones then created). The API results for a zone GET includes MaxNumberOfRecords. It would also be useful to be able to retrieve MaxNumberOfZones for the DNS provider in a subscription.

    7. Allow modifying TTL per record instead of per record-set

      Real-world scenarios need different TTL values per record in the same zone. The service currently allows only to define TTL per record-set that is not bad, but not good enough.

    8. Allow increase of DNS alias quota

      Currently there is a hard limit of 20 DNS alias records per public IP. This quote is not documented anywhere, nor is it able to be changed by any support staff.

    9. Azure DNS should not be listed as globally available

      According to

      https://azure.microsoft.com/en-us/regions/services/

      Azure DNS, as a service, is globally available. However, as stated by a Microsoft support engineer here

      https://social.msdn.microsoft.com/Forums/en-US/a26ca6e1-28a6-44f1-8807-6fdd6bdae66f/

      it isn't. The service availability chart should reflect this.

      Thank you for the feedback.

      The intent of the ‘global’ availability for Azure DNS is to indicate that is available as part of the Azure Public cloud, but not tied to any specific region. However, I appreciate that this can easily be misunderstood as meaning the service is available in Azure National Clouds, which it is not (as yet).

      I’ll share your feedback with the page owners.

    10. Roelant

      when adding endpoints to the traffic manager, you get all app-services that are available, but in our case, the list is very long, and searching makes it difficult. The list is not sorted, and neither can we filter it.
      Adding a filter would be very helpfull.

    11. traffic manager api

      I would like an API call that can be made to get the list of traffic manager IP addresses. (this list https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-faqs#what-are-the-ip-addresses-from-which-the-health-checks-originate.)

      That way we can automate the checking of this list and alert if it is amended, and also automate updating our azure services. Just having a website to check is too manual.

    13. Ability to set a TTL value to Automatic

      I've never seen this option in a DNS service but I always thought it would be cool to have an automatic TTL setting that would work like this:

      Whenever I change a record, if I had the TTL on Auto then it would lower the TTL to something like 5 minutes. Then each week after it would double it until it was finally up to some max value (it would be nice also if I could optionally specify the max value).

      The scenario I have for this are cases like domain name transfers, or any time I'm setting up some…

    14. add source port for every conversation in Traffic Analytics dashboard

      Currently sessions are summarized for source IP to desination IP+port. There is source port missing in that schema which would allow for recognition of separate conversations to the same client+service pair.

    17. show destination public IPs in Traffic Analytics

      Currently, there is summarization done for destination public IPs and only destination region is visible in Traffic Analytics. Sessions to different public IPs are not separated in the dashboard, hence summary outgoing volume can be viewed only.

    18. Use "DNS name" in downloaded RDP file instead of IP address

      I have created a VM with a "DNS name". Connecting to it with the "Connect" button downloads an RDP file, but the RDP only uses the IP address of this VM.

      When I shutdown the VM and restart it on another day the IP address has changed.

      It would be super convenient that Azure just uses the "DNS name" entry for the RDP file.

    20. Develop a tool that will import DNS zone files hosted at other providers like Route53

      Since many DNS providers do not allow you to export your zone files create a utility that will harvest them in a format that could be used to import them into Azure DNS.
