I'm struggling to get to grips with Reserved IP addresses in an Azure Cloud Service.
I have a Cloud Service with Staging and Productions deployments and I need at least the Production deployment to have a stable IP address. I set up 2 Reserved IP addresses as described here then assigned my reserved IPs to the Production and Staging deployments with Power Shell:
Set-AzureReservedIPAssociation -ReservedIPName MyReservedIP1 -ServiceName mycloudservice -Slot “Production”
Set-AzureReservedIPAssociation -ReservedIPName MyReservedIP2 -ServiceName mycloudservice -Slot “Staging”
All well and good the reserved IPs get assigned to the respective instances and swapping maintains the correct addresses. The problem is if I delete one of the deployments and redeploy the IP address is not maintained.
I also tried assigning a reserved IP address to the cloud service without specifying a "Slot" and it assigned fine but does not seem to get used in either Production or Staging deployments.
Set-AzureReservedIPAssociation -ReservedIPName MyReservedIP -ServiceName mycloudservice
My usual workflow would be to deploy to Staging then swap with Production once I have tested all is working fine. With this scenario how can I ensure the Production deployment always gets a Reserved IP address when I swap from Staging, even if there is no current Production instance deployed?
The Azure documentation says "IP address for the cloud service will be the same even as resources are shutdown or deallocated" so shouldn't my previously assigned Production IP address be maintained even if I delete the Production instance and then swap from Staging?
This worked for me:
Create your reserved IPs
New-AzureReservedIP -ReservedIPName "ip1" -Location "East US 2"
New-AzureReservedIP -ReservedIPName "ip2" -Location "East US 2"
Deploy to the production slot with the following network configuration in your .cscfg file:
<NetworkConfiguration>
<AddressAssignments>
<ReservedIPs>
<ReservedIP name="ip1" />
</ReservedIPs>
</AddressAssignments>
</NetworkConfiguration>
Deploy to the staging slot with the following configuration:
<NetworkConfiguration>
<AddressAssignments>
<ReservedIPs>
<ReservedIP name="ip2" />
</ReservedIPs>
</AddressAssignments>
</NetworkConfiguration>
Continue using your normal workflow - deploy to staging, then swap to production. The IP addresses should stay associated with their slots (ip1 in production and ip2 in staging).

I have a Cloud Service Worker Role in Azure which has been set up with a Reserved IP address. The goal of the Reserved IP is so when the worker role makes external requests it will always come from the same IP. No external traffic is received by the service and no internal communication is required.
EDIT: The Reserved IP was associated with the Cloud Service using the following Azure Powershell command:
Set-AzureReservedIPAssociation -ReservedIPName uld-sender-ip -ServiceName uld-sender
This added the following NetworkConfiguration section into the .cscfg file:
<NetworkConfiguration>
<AddressAssignments>
<ReservedIPs>
<ReservedIP name="uld-sender-ip" />
</ReservedIPs>
</AddressAssignments>
</NetworkConfiguration>
Now, when I try and re-deploy the service or update the configuration settings in Azure, I get the following error:
The operation '5e6772fae607ae0ca387457883bf2974' failed: 'Validation
Errors: Error validating the .cscfg file against the .csdef file.
Severity:Error, message:ReservedIP 'uld-sender-ip' was not mapped to
an endpoint. The service definition must contain atleast one endpoint
that maps to the ReservedIP..'.
So, I have tried adding an Endpoint to the .csdef file like so:
<Endpoints>
<InternalEndpoint name="uld-sender-ip" protocol="tcp" port="8080" />
</Endpoints>
In addition, I have entered NetworkTrafficRules to the .csdef like so:
<NetworkTrafficRules>
<OnlyAllowTrafficTo>
<Destinations>
<RoleEndpoint endpointName="uld-sender-ip" roleName="Sender"/>
</Destinations>
<AllowAllTraffic/>
</OnlyAllowTrafficTo>
</NetworkTrafficRules>
But I still get the same error.
My understanding is that endpoints are only required for internal communication between worker/web roles, or to open a port to receive external communication.
EDIT: My question is how do you map a Reserved IP to an Endpoint for this scenario?
To avoid getting the error while trying to update the configuration settings or re-deploy the service, I ran the Azure Powershell command to remove the reserved ip association with the service:
Remove-AzureReservedIPAssociation -ReservedIPName uld-sender-ip -ServiceName uld-sender
Then I was able to edit and save the configuration settings in Azure, and/or re-deploy the service. Once the service is updated I ran the Azure Powershell command to set the reserved ip association with the service:
Set-AzureReservedIPAssociation -ReservedIPName uld-sender-ip -ServiceName uld-sender
This is obviously not the ideal solution but at least I can make changes to the service if needed. Hope this helps someone.
I am trying to associate a reserved IP with an App Service and NOT a VM.
I have successfully created a reserved IP, but unable to associate it to an existing App Service.
Here is the list of commands I am using in windows power shell.
> Add-AzureAccount (successful)
> Select-AzureSubscription (successful)
> New-AzureReservedIP –ReservedIPName PrevigeoWebReservedIP –Location
"North Europe" -ServiceName XXX (unsuccessful)
> Get-azureservice -servicename XXX (unsuccessful)
My question is: Is it conceptually wrong to associate a reserved IP address to a App Service? Is it possible only with a VM?
Is it possible to associate a reserved IP to an App Service, what am I missing here?
I am sure that the App Service with name XXX is present in the Azure subscription. I have only one subscription as a matter of fact.
Windows power shell version is:

[Update] Background: I am doing this to restrict only our Azure Wep App to access our Azure API App. I am trying to achieve this using the ipconfig element in web.config file. For this to work, I believe that we need have static outbound IP addresses, which are not shared by other tenants (else it will be a security issue). In this context, I am not sure if a static inbound IP will help us.
Azure Web Apps work within a multi-tenant environment. So, in general, you cannot assign a reserved IP address to a Web App.
If you set up an IP-based SSL certificate, then a dedicated inbound IP address will be assigned to your web app. Not quite the same as a reserved IP (since it's not one you create/assign).
I have an Azure Cloud Service, and a Azure Virtual Network with Subnet.
I can deploy the Cloud Service onto the Virtual Network by setting the appropriate configuration setting in the .cscfg.
What I'm struggling with though is bringing the role onto a specific IP address. My guess is that it's currently using DHCP to get an IP address.
I've tried using the following Powershell:
Get-AzureVM -ServiceName myrole | Set-AzureStaticVNetIP -IPAddress 127.16.0.4 | Update-AzureVM
But the IP address never changes:
<IpAddress>172.16.0.5</IpAddress>
Is there a restriction on doing this on cloud services?
Any help would be really appreciated.
Thanks,
Graeme
Network configuration schema for Cloud Service is documented here.
https://msdn.microsoft.com/library/azure/jj156091.aspx
As you'll see, you have the ability to specify a ReservedIP but not a static private IP.
My understanding is that Set-AzureStaticVNetIP works for Azure IaaS VM, not for Cloud Service VM.
Virtual machines whether there are IaaS or Paas provisioned in a VNET are always allocated the first available IP address in the subnet after the first 4 addresses which are reserved from .0 to .3.
So considering your request, I will define subnets that enable to target the right subnet IPs for my role instances, and if I need to precisely know which IP is used by which instance, read it in the "role start" method and use it to configure whatever solution you need for this IP to be be "static".
Hope this helps
Best regards

What I have read so far on the web is that there is no way to add a reserved IP to an existing VM (unless I recreate the VM which I am trying to avoid). However, I have noticed that external IP of my VM and the cloud service is same.
Reserved IP Addresses page explains how to "To use a Reserved IP with Cloud Services". I have looked everywhere in the Azure Management Portal but couldn't find a configuration setting for Service Configuration Schema.
I am using the Azure scheduler to turn-off the VMs at night and on the weekends. From the following I understand is that there is something that I need to write in the scheduler script to re-assign the Reserved IP when the VM starts in the morning. Did I get it right?
Shutdown VM - Previously, when all the Virtual Machine instances in a
cloud service were moved to the Shutdown state (stop/deallocated), the
public IP would be released and a new public IP would be assigned when
one of the Virtual Machines instances was started. However, with this
release, if the VM uses a Reserved IP, then the Reserved IP can be
used when re-deploying the VMs.
P.S. Is Stack Overflow the best place to ask this sort of questions relating to Azure or shall I use Server Fault in the future? I have seen Azure questions in both websites.
At Build 2015 they announced this is now possible and VERY easy.
Simply open Azure powershell and run this:
New-AzureReservedIP -ReservedIPName "ipname" -Location "West US" -ServiceName "somevm"
If you run this it will reserve an IP named "ipname" and associate it with the already deployed instance "somevm.cloudapp.net"
In order to assign existing reserved IP to an existing VM, you can use the following command:
Set-AzureReservedIPAssociation -ReservedIPName MyReservedIP -ServiceName TestService
Step by step to create Reserved IP and using it on Azure VM. Here you can go
Reserved IP Creation
I have done the Elastic IP Automatic scheduling on AWS.Here is the reference link Elastic IP Automation on AWS script.
Between needs to check about How can I write a script for automating the reserved IP for Azure.If you had done it earlier, Kindly share the script this will be very useful. Thanks.
At this point, we don't support the capability to associate a Reserved IP to an already existing VM.
We are currently working on the capability to reserve the IP of an existing VM.

For new VMs (with resource manager) you should do the following:
Create new static IP address:
$ip = New-AzureRmPublicIpAddress -Name "<ip-name>" -ResourceGroupName <group-name> -Location eastus -AllocationMethod Static
Get information about VM Network Interface:
Get-AzureRmVM -ResourceGroupName <group-name> -Name <vm-name> | Select -ExpandProperty NetworkProfile
Get corresponding network interface and set new ip and update NIC:
$netInt = Get-AzureRmNetworkInterface -ResourceGroupName "group-name" -Name <nic-name>
$netInt.IpConfigurations[0].PublicIpAddress = $ip
Set-AzureRmNetworkInterface -NetworkInterface $netInt
I read all of the previous entries and did not come away with a clear picture of how to proceed with assigning a reserved IP address to my existing Azure classic VM, so I opened a support ticket. I got excellent clear guidance from "Sruthi Saranya K", a support engineer in Azure Networking. Sruthi stated "in classic deployment model it is not possible to have a static public IP assigned to a VM", which I had read elsewhere, but she clarified that you simply assign the IP address to the cloud service and not the VM directly, then the VM will automatically pick up on the change. I outline all of the commands here for your convenience, starting from an Azure PowerShell prompt. The critical command was specified in the top response here, but not all of the steps. Also, that example also includes specifying the service, but it does not appear to be a supported parameter for that command, instead there is a second command to associate the IP with the service.
add-azureaccount (to log in to Azure from PowerShell)
New-AzureReservedIP -ReservedIPName "ipname" -Location "East US"
get-azurereservedip (just to see what the reserved IP address is)
Set-AzureReservedIPAssociation -ReservedIPName "ipname" -ServiceName "your cloud service name"
Also, depending on the use, you may want to look up the IP address on mxtoolbox.com to make sure it is not already blacklisted. My reserved IP was for a web site, but the default # DNS entry for the domain meant our domain was generally going to be associated with that IP address, and previously our mail has been blacklisted because our web server IP address was sullied by some other Azure tenant. If you get a blacklisted address, you can remove it and get a new one, also a suggestion from Sruthi. Here are the commands to remove the reserved IP, and to remove the cloud service association if needed:
remove-azurereservedip
Remove-AzureReservedIPAssociation
My sincere thanks to Sruthi for making it so simple and preventing an unnecessary redeployment of our company's public web server.
Add Public IP to an Existing VM
Log into the portal
Find the Resource Group (RG) where your VM is Located
Confirm your VM has a network interface - if not, create one (it should have one)
Create a Public IP Address (static or dynamic, doesn't matter) by adding one to your RG from the marketplace (do this first so it is creating while you make your NSG).
Create a Network Service Group by adding one to your RG from the marketplace and associating it with your VM.
Once the NSG has deployed, go back to the Overview of your PIP and click the "Associate" button in the info section of the blade.
Select the Network Interface of your VM you validated in step 3.
Get a cup of coffee or something, it will be a minute, but otherwise you're done.
New-AzureReservedIP -ReservedIPName "nameIP" -Location "East US" -ServiceName "azureA2vm"
Get this:

Check PowerShell version. Update to latest version.
Does anyone knows if obtaining a static IP address for a Web or Worker Role on Windows Azure is possible (possibly only in private beta)?
A few years later, Azure now lets you reserve IP addresses for VMs and cloud services (Web and Worker roles). However, it is only accessible from PowerShell for the time being (this will change in the future, apparently).
The first five static IP addresses are free. To create an IP you will need to make sure you have the latest version of the Azure PowerShell command-line interface and also have your Azure account linked to Azure PowerShell (outside the scope of this post but not hard).
To Create a new IP in PowerShell:
$ReservedIP = New-AzureReservedIP -ReservedIPName "FirewallIP" -Label "WebAppFirewallIP" -Location "Japan West"
To associate it with a VM:
New-AzureVMConfig -Name "WebAppVM" -InstanceSize Small -ImageName $images[60].ImageName | Add-AzureProvisioningConfig -Windows -AdminUsername cloudguy -Password Abc123 | New-AzureVM -ServiceName "WebApp" –ReservedIPName $ReservedIP -Location "Japan West"
To insert your new IP into a Web or Worker Role (if the worker role has an external endpoint), add the following to ServiceConfiguration.Cloud.cscfg:
<ServiceConfiguration>
<NetworkConfiguration>
<AddressAssignments>
<ReservedIPs>
<ReservedIP name="<reserved-ip-name>"/>
</ReservedIPs>
</AddressAssignments>
</NetworkConfiguration>
</ServiceConfiguration>
To view an IP at any time:
Get-AzureReservedIP -ReservedIPName "FirewallIP"

There's an update to this story. Back in October 2011, Microsoft announced improved in-place updates to existing deployed services (announcement here). You can now update your deployment in several ways without having the assigned IP address changed. For example:
Grow/shrink Role size
Increase local storage size
Change endpoints
Add / remove roles
Once you deploy: As long as you don't delete your deployment, your IP address will stay as-is.
Unfortunately, this is not possible for the time being... If you need to do IP-based access control, you could open a support call and request the current IP address range for a given datacenter, but there is no real guarantee it won't change over time.
