    1. Azure DNS needs DNSSEC support

      DNSSEC is required to be able to secure your DNS requests. At the moment this is not available. We cannot move until our domains to Azure DNS untill these requirements have been met.

    2. Azure should be its own domain registrar

      Windows Azure should offer domain registrar services so users don't have to maintain our domain names with a separate company. This also has the potential to greatly streamline the process of setting up a website on Azure.

    3. Extend Azure DNS to support zone transfers so it can be used as seconday DNS

      If Azure DNS supported zone transfers, then if could be used both as a reliable secondary DNS service, or as an external proxy service for AD split-brain, or on-premise hosted DNS configurations.

      Thanks you for the suggestion. This remains a key backlog item for us.

      We’d be interested in further input via your comments. Please consider the following questions:
      – Do you require zone transfers in to Azure DNS, or zone transfers out? Why?
      – Do you require AXFR or IXFR?
      – How should zone transfers be secured?

    4. Provide a 301 (Permanent) redirect service for apex (naked) domains

      Discussed in the Azure DNS docs: https://azure.microsoft.com/en-us/documentation/articles/dns-getstarted-create-recordset/#comment-2294403853

      Right now, you must use a static IP address if you want to point an apex (naked) domain (e.g., mycompany.com) to a Cloud Service (e.g., mycloudservice.cloudapp.net). Static IP's are stable as long as the Cloud Service isn't deprovisioned; however, for maximum security, simplicity, and maintainability (i.e., even if a cloud service is deprovisioned), it would be awesome if we could have 301 redirects for the apex domain to a the www CNAME endpoint and not need to be concerned with the IP address of the Cloud Service at all. The scenario goes like…

    5. Traffic Manager Failover profile alert

      Can you please add alert rule for Azure traffic manager to update the co-admin by sending mail alert whenever there is a down of primary / secondary and switch over?

      Since our customer wants to create alert for this scenario.

      This will greatly relax the customer to sit in a place to watch service changes through mail.

    6. Possibility to set a DNS Suffix on Azure networks (like DNS Servers)

      There are many scenarios for Virtual Machines (and Other maybe) where NIC settings are cleared (VM Deallocated). DNS Servers can be set on Azure Network, and this VM will have DNS Servers settings via DHCP. But we have to set DNS Suffix manually each time, or set a script automatically at each boot.
      The idea is just to have a way to set a suffix DNS for VM Networks, with the same way as DNS Servers. With this settings, DHCP will assign DNS suffix to all VM automatically.

    7. Introduce 'Vanity name servers'

      We would like to see an introduction of delegations using name server names in our own zone (sometimes called 'vanity name servers').

      Using 'vanity name servers' are important for consolidating our corporate brand.

      Currently, the 'host' field of the SOA and the NS records at the zone apex are deliberately locked to discourage us from setting up delegations other than via the Azure DNS name server names.

      We realise such delegations would break were we ever to change the Azure DNS name server IP ranges in future, which would obviously need to be resolved prior to the introduction of this.

    8. Enable split DNS for providing both public and internal name resolution to VMs in the VNET.

      Amazon Route 53 supports split-view DNS, so you can configure public and "PRIVATE" hosted zones to return different external and internal IP addresses for the same domain names.
      i think a similar capability can be very useful also in Azure

    9. Azure DNS query log

      Hi,

      I would like to request Azure DNS Query Log. This will help us identify traffic hitting record name in the dns zone.

      Possible Log Sample

      Time-Stamp,SourceIP,RecondType,RecordName

    10. Traffic Manager Logging & Alerts

      Traffic Manager needs to keep track of past endpoint health failures.
      In addition to this it should be possible to configure alerts about changes to endpoint health.

    13. Introduce CNAME flattening

      Does
      #Azure
      #DNS
      support CNAME flattening #CloudFlare
      style? The answer is no yet it would be a very handy feature.

      See here for more details on how CloudFlare is doing it, and they might actually have introduced the whole notion of "CNAME flattening": https://support.cloudflare.com/hc/en-us/articles/200169056-CNAME-Flattening-RFC-compliant-support-for-CNAME-at-the-root

    14. Add more configurability to Traffic Manager monitoring endpoint

      I would like for the monitoring endpoint configuration to support two new options:

      1) How many consecutive times TrafficMgr does not get an http 200 from the endpoint before it deems it down. I have a scenario where I want it to be deemed down immediately after one failure for a quicker failover.
      2) How many consecutive times TrafficMgr receives an http 200 after it has deemed it down before it will deem it up again. I have seen a scenario where table storage (or SQL Azure) is inconsistent (fails one query then succeeds the next, back and forth) and…

    15. azure zones dns-forwarder

      Please extend DNS zones solution to add forwarding & client features to implement the following in PaaS instead of with VMs:
      https://github.com/Azure/azure-quickstart-templates/tree/master/301-dns-forwarder

      Use case: use azure dns to forward dns queries to 168.63.129.16 & between subnets. Enterprise DNS would forward to Azure DNS. VNET has Azure-provided name resolution (*.internal.cloudapp.net). In this way Enterprise DNS could dynamically learn of a PaaS offering on VNET.

    16. Allow Traffic Manager to Support Absolute Monitoring Endpoints

      Current endpoint monitoring in Traffic Manger only supports a relative path. For flexibility, it would be great to support a full url path like http://www.example.com/health

    17. Create private dns zone in virtual network which already has VMs

      Create private dns zone in virtual network which already has VMs. Currently, it's giving below error:

      `Virtual networks that are non-empty (have Virtual Machines or other resources) are not allowed during association with a private zone.`

    18. Add DNS name label to private IPs

      Currently when using Azure provided DNS all VM's are registered automatically using VM name. Unfortunately it's not possible to register other resources like for example load-balancers with private IPs. It would be great to be able to assign dns name to private IPs

    19. Provide statistics to Azure DNS Services

      Azure DNS Service has no statistics about requests, type of requests, origin of requests and so on ...
      That can be useful to keep track of service costs and also to have a general view of our IaaS usage.

    20. Azure Private DNS Zone resolution from OnPremise

      Make it possible to enable the Name Resolution from onpremise if i have an azure private dns Zone.

      It should be possible to make an Forward from onpremise dns to an azure private dns Zone.
