 # Manage a public IP address prefix
 
-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 from the prefix and associate the address to Azure resources. For more information, see [Public IP address prefix overview](public-ip-address-prefix.md).  This article explains how to create, modify, or delete public IP address prefixes, as well as creating public IPs from an existing prefix.

 ## Create a public IP address prefix
 
 The following section details the parameters when creating a public IP prefix.

-   |---|---|---|
-   |Subscription|Yes|Must exist in the same [subscription](../../azure-glossary-cloud-terminology.md?toc=%2fazure%2fvirtual-network%2ftoc.json#subscription) as the resource you want to associate the public IP address to.|
-   |Resource group|Yes|Can exist in the same, or different, [resource group](../../azure-glossary-cloud-terminology.md?toc=%2fazure%2fvirtual-network%2ftoc.json#resource-group) as the resource you want to associate the public IP address to.|
-   |Name|Yes|The name must be unique within the resource group you select.|
-   |Region|Yes|Must exist in the same [region](https://azure.microsoft.com/regions)as the public IP addresses you'll assign addresses from the range.|
-   |IP version|Yes| IP version of the prefix (v4 or v6).
-   |Prefix size|Yes| The size of the prefix you need. A range with 16 IP addresses (/28 for v4 or /124 for v6) is the default.

 >[!NOTE]
 >In regions with availability zones, you can use PowerShell or CLI commands to create a public IP address prefix as either: non-zonal, associated with a specific zone, or to use zone-redundancy.  For API version 2020-08-01 or later, if a zone parameter is not provided, a non-zonal public IP address prefix is created. For versions of the API older than 2020-08-01, a zone-redundant public IP address prefix is created.
