    1. Create Elastic IPs so we can actually create web addressable apps with full DNS, not *.cloudapp.net

      Right now, you can't use DNS to make your primary web app run seamlessly on Azure. Azure needs to add elastic IPs so you can point a mydomain.com at an Azure IP, instead of the current *.cloudapp.net requirement.

      We do support Static Public IPs in Azure today that is equivalent to Elastic IP in AWS. Static Public IPs can be mapped to a VM’s NIC (elastic IP equivalent) or to a load balancer’s Front end IP.

      Azure DNS (preview feature) allows you to map an IP address (as opposed to an cloudapp.net domain) to a custom DNS name.

      The request made here is satisfied by combining the two solutions explained above.

    2. Allow multiple reserved IP addresses be assigned to a single VM

      Currently you can only have one reserved (static) public IP for a given Azure VM. This limits any case where you would want to run multiple SSL enabled sites/applications on the standard 443 port.

      I understand there is support for SNI SSL with host headers but not all applications and devices support this feature. Current competition in you market allow up to 5 IPs. A limit I believe is still arbitrarily low given the power of your larger VM instances available.

    4. Reserved IP geo-location

      A reserved IP address, although associated to a region (-Location) during creation time could come from any geographic location. For example, a reserved IP address associated with 'North Europe' region could show up as located in Brazil when using IP geo-location services. Please fix this issue as any reserved IP-bound service is unable to access resources that are protected by IP geo-blocking software (that blocks the reserved IP as it lies outside the acceptable territory for the resource).

    5. Multiple IPs per NIC

      This would enable use of hosting multiple VIPs or SSL sites on a server w/o the use of host headers. 3rd party load balancers such as F5 simply cannot match on-prem capability without this.

      Amazon has supported this since 2012

    6. Virtual Network IP Management Interface

      Please provide a gui that displays IP Address assignments across VNETs. Showing what's dynamic and what's "static". This will help in large deployments where many static entries exist and for mgmt purposes.

    8. multiple public IP

      Allow secondary NICs to have public IPs. We're trying to deploy Palo Alto Network appliances as a VPN endpoint and it requires dual-NIC each with a public IP address. PA's reference architecture uses a NAT server to provide a second public interface. This is not idea since we have to manage multiple servers and routes. The completed multi public IP feature allows multiple public IPs on the same NIC. We're looking for public IPs on multiple NICs.

    10. Increase limit for Public IP by Virtual Machine

      Increase limit for Public IP by Virtual Machine, today we can set just one IP for each VM. Sometimes it is important to get more IP by instance, mainly when I've many websites on some host. We could to create other VIPs.

    11. Add Multiple External IP Support to load balancer via Portal

      Although you can add additional External IPs via Powershell, you should be able to allocate multiple external IPs via the portal.

    13. Support Reserved IP's with v2 infrastructure or allow transition from Reserved to Public

      We currently use a Reserved IP with a cloud service. We're moving to a new infrastructure that uses a load balancer which only takes a Public IP. This means we have to update our customers with a new IP address.

      Please either support Reserved IP's in the same places that Public IP's are supported, or allow some kind of transition from Reserved IP's to Public IP's.

      The ability to migrate classic reserved IP address to Public IP is now available and described in Move-AzureReservedIP command here: msdn.microsoft.com/library/mt786752.aspx
      Thank you for your help in guiding Azure Networking features.

    14. Allow a VM to have a reserved static public IP and not just a load balancer

      As per the title, allow a VM to have a reserved address (as we could do for v1). If I use a load balancer, i would have a huge number of rules to setup. In the old v1 I could assign a reserved address but I would have a problem with setting the large number of rules I need as endpoints. V2 solved that for me with Network Security Groups and the ability to have to specify a range of ports on a single line, but I need a reserved IP at the VM level.

    15. Add Azure and AWS IP ranges to easily restrict traffic without using Powershell

      Currently adding Azure or AWS IP addresses need to be done by Powershell commands and also need to be updated every time an IP Address change. People need this to be easily configurable

    16. Private IP displays in dashboard.

      It would great if private IP displays in dashboard/first pages, instead of multiple click to see the private IP address.

    17. Allow creating virtual interfaces (IP addresses) in Linux network environment

      Currently adding virtual interfaces, i.e. eth0:1, eth0:2, etc. on top of the physical network interface in linux is not possible within azure vnet. Such thing limits the use of "floating IP" scenario where one ip address can be assigned to either of two nic's, depending on their availbility, e.g. HA setup of HAProxy.

      Thank you for your suggestion. This feature- the ability to add multiple IP endpoints to a single NIC- is now in Preview and will soon be generally available.
      You can find out more about this feature and using multiple IP Configurations on a NIC at the documentation links below.
      The documentation also describes the steps to register your Azure subscription to preview this feature today.

      Documentation for Assign multiple IP addresses to virtual machines:
      https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-multiple-ip-addresses-portal
      https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-multiple-ip-addresses-cli

      https://docs.microsoft.com/en-in/azure/load-balancer/load-balancer-multiple-ip

    18. Add a feature that gives you an static IP regardless of what server you attach to it.

      Add a feature that gives you an static IP regardless of what server you attach to it. That wat, if you have to migrate your server you keep your IP Address.

    19. enable assigning a reserved IP_address to a public IP address

      There are 2 ways to reserve an IP address:

      https://portal.azure.com/#blade/HubsExtension/BrowseResourceBlade/resourceType/Microsoft.ClassicNetwork%2FreservedIps/scope/
      ( I call it classic IP adress from now)
      and

      https://portal.azure.com/#blade/HubsExtension/BrowseResourceBlade/resourceType/Microsoft.Network%2FPublicIpAddresses/scope/
      ( I call it the public IP address from now)

      My suggestion is to be able to use a previously registered classic IP address for assigning it to a public IP adress.
      Right now, you can only create "new" public IP adresses by registering new IP adresses, but I would like also be able to keep my classic IP adresses.

    20. All Azure quotes should be exposed via API and portal. For example the number of frontend IP addresses allowed on an external load balancer

      All Azure quotes should be exposed via API and portal. For example the number of frontend IP addresses allowed on an external load balancer

      All Azure quotas should be exposed via API and portal.
      For example the number of frontend IP addresses permitted for an external load balancer is not exposed in the portal, via Powershell or even API.
      This makes it easier to anticipate when nearing a configured quota.
