Quickstart: Create a public IP address prefix using PowerShell

  • Article

Learn about a public IP address prefix and how to create, change, and delete one. A public IP address prefix is a contiguous range of standard SKU public IP addresses.

When you create a public IP address resource, you can assign a static public IP address from the prefix and associate the address to virtual machines, load balancers, or other resources. For more information, see Public IP address prefix overview.

Prerequisites

  • An Azure account with an active subscription. Create an account for free.
  • Azure PowerShell installed locally or Azure Cloud Shell

If you choose to install and use PowerShell locally, this article requires the Azure PowerShell module version 5.4.1 or later. Run Get-Module -ListAvailable Az to find the installed version. If you need to upgrade, see Install Azure PowerShell module. If you're running PowerShell locally, you also need to run Connect-AzAccount to create a connection with Azure.

Create a resource group

An Azure resource group is a logical container into which Azure resources are deployed and managed.

Create a resource group with New-AzResourceGroup named QuickStartCreateIPPrefix-rg in the eastus2 location.

$rg =@{
    Name = 'QuickStartCreateIPPrefix-rg'
    Location = 'eastus2'
}
New-AzResourceGroup @rg

Create a public IP address prefix

In this section, you create a zone redundant, zonal, and non-zonal public IP prefix using Azure PowerShell.

The prefixes in the examples are:

  • IPv4 - /28 (16 addresses)

  • IPv6 - /124 (16 addresses)

For more information on available prefix sizes, see Prefix sizes.

Create a public IP prefix with New-AzPublicIpPrefix named myPublicIpPrefix in the eastus2 location.

IPv4

To create a IPv4 public IP prefix, enter IPv4 in the -IpAddressVersion parameter. To create a zone redundant IPv4 prefix, enter 1,2,3 in the -Zone parameter.

$ipv4 =@{
    Name = 'myPublicIpPrefix'
    ResourceGroupName = 'QuickStartCreateIPPrefix-rg'
    Location = 'eastus2'
    PrefixLength = '28'
    IpAddressVersion = 'IPv4'
    Zone = 1,2,3
}
New-AzPublicIpPrefix @ipv4

IPv6

To create a IPv4 public IP prefix, enter IPv6 in the -IpAddressVersion parameter. To create a zone redundant IPv6 prefix, enter 1,2,3 in the -Zone parameter.

$ipv6 =@{
    Name = 'myPublicIpPrefix'
    ResourceGroupName = 'QuickStartCreateIPPrefix-rg'
    Location = 'eastus2'
    PrefixLength = '124'
    IpAddressVersion = 'IPv6'
    Zone = 1,2,3
}
New-AzPublicIpPrefix @ipv6

Create a static public IP address from a prefix

Once you create a prefix, you must create static IP addresses from the prefix. In this section, you create a static IP address from the prefix you created earlier.

Create a public IP address with New-AzPublicIpAddress in the myPublicIpPrefix prefix.

To create a IPv4 public IP address, enter IPv4 in the -IpAddressVersion parameter.

$pf =@{
    Name = 'myPublicIpPrefix'
    ResourceGroupName = 'QuickStartCreateIPPrefix-rg'
}
$prefix = Get-AzPublicIpPrefix @pf

$ipv4 =@{
    Name = 'myPublicIpAddress'
    ResourceGroupName = 'QuickStartCreateIPPrefix-rg'
    Location = 'eastus2'
    Sku = 'Standard'
    Tier = 'Regional'
    AllocationMethod = 'Static'
    IpAddressVersion = 'IPv4'
    PublicIpPrefix = $prefix
}
New-AzPublicIpAddress @ipv4

Note

Only static public IP addresses created with the standard SKU can be assigned from the prefix's range. To learn more about public IP address SKUs, see public IP address.

Delete a prefix

In this section, you learn how to delete a prefix.

To delete a public IP prefix, use Remove-AzPublicIpPrefix.

$pr =@{
    Name = 'myPublicIpPrefix'
    ResourceGroupName = 'QuickStartCreateIPPrefix-rg'
}
Remove-AzPublicIpPrefix @pr

Note

If addresses within the prefix are associated to public IP address resources, you must first delete the public IP address resources. See delete a public IP address.

Clean up resources

In this article, you created a public IP prefix and a public IP from that prefix.

When you're done with the public IP prefix, delete the resource group and all of the resources it contains:

Remove-AzResourceGroup -ResourceGroupName 'QuickStartCreateIPPrefix-rg'
