    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.

        Thanks for the suggestion. We recognise the strategic importance of DNSSEC and it is a key feature on our long-term backlog.

        DNSSEC represents a very large engineering investment, and hence we have to prioritize carefully vs other work. The most customer data we can get supporting the need for DNSSEC support, the better prioritization decisions we can make. We appreciate your votes and your comments.

      • 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.

        • Support apex (naked) domains more seamlessly

          Some things work, other things don't. I can setup an apex domain, but to get SSL working on an apex domain in hosted cloud service web role requires tweaking. Traffic manager doesn't work with apex domains.
          Azure needs a DNS service like Amazon's Route 53. (http://aws.amazon.com/route53/)

          • 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?

            • Add CAA record

              Add the ability to add a CAA record! This is now becoming more important with Qualys flagging it as a "requirement".

              • Traffic Manager for SQL Database

                The traffic manager is a great way to account for failover between web nodes in different data centers. However, an analogous paradigm doesn't exist for databases. In the premium tier, you can enable active geo-replication. However, all applications dependent on the primary either need to have their connection strings changed over when failing over between data centers, or they have to have some sophisticated retry logic built in at the application tier. It would be great if applications could point to a single, consistent endpoint and the geo-failover could be handled at a higher level the way it is with…

                • 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.

                  • 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.

                    • 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

                      • 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.

                        • 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…

                            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…

                            • traffic manager support for external endpoints that are IP addresses instead of FQDN

                              Support for IPs to be used instead of FQDNs for Azure Traffic Manager external endpoints would reduce the DNS lookup penalty of the external endpoint. Right now 3 DNS lookups are needed: 1, foo.com 2, foo.trafficmanager.net 3, foo-vip.externalendpoint.com

                              Supporting foo.trafficmanager.net pointing to the IP for #3 eliminates the DNS lookup for #3 in the example above

                                Thank you for the feedback. We are considering this, it is a required feature for supporting ‘naked’ domains in Traffic Manager (another requested feature).

                                In the meantime, the latency of the lookups you describe can be reduced in practice by using long TTLs on all except the <..>.trafficmanager.net DNS entry, so that the other DNS records are typically retrieved from the local DNS cache.

                              • 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.

                                  We need the new configuration in Azure Traffic Manager.

                                  • Generic TCP/UDP protocols for Monitor settings

                                    Hello,

                                    I am configuring a generic TCP services with traffic manager. It looks like the service is working perfectly fine and client sessions are directed correctly to the nearest server/azure datacentre; however monitoring of the service seems to be available only for HTTP/HTTPS services.

                                    This is not going to work for generic TCP services and traffic manager believes that the service is degraded/offline whereas the service is running perfectly fine.
                                    I highly suggest to make the monitoring of the traffic manager services available for generic TCP/UDP services as well.

                                      Thanks for the suggestion. We’ll certainly consider this. We’d be interested in votes and comments from other users on this topic.

                                    • Formalize the Traffic Manager user agent string

                                      I would like to see the user agent that Traffic Manager uses in its HTTP requests as part of monitoring/probing become formalized so that applications can take a dependency on the user agent string name and not worry about it changing in the future affecting the application that has behavior that depends on the user agent.

                                      For an example where the user agent string is needed to comply with URL canonicalization needs along with Traffic Manager being involved, please refer to http://social.msdn.microsoft.com/Forums/azure/en-US/d9f8e779-644d-4263-990c-9de5a7cf403c/is-the-user-agent-for-traffic-manager-guaranteed.

                                      • Alias records

                                        I have a number of DNS records for various webapps in my zone... all of which point to the same host. I understand the limitations CN's, but the convenience of maintaining them is too great.

                                        My request is to provide an "alias" record, which provides a single record to maintain, but is applied as A/AAAA records.

                                        The benefit is to bridge CNAME convenience with RFC incompatible goals such as CN apex records.

                                        • 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

                                          • Support edns-client-subnet extension in Traffic Manager

                                            I'm surprised to learn the Traffic Manager does not support the client-subnet feature. Most major CDNs & DNS providers seem to support it.
