custom IP address prefix is a contiguous range of IP addresses owned by using an external customer and provisioned into a subscription. Microsoft is approved to advertise the range. Addresses from a custom IP address prefix can be used in the equal way as Azure owned public IP address prefixes. Addresses from a custom IP address prefix can be related to Azure resources, interact with internal/private IPs and virtual networks, and attain external destinations outbound from the Azure Wide Area Network.
- Customers can hold their IP ranges (BYOIP) to maintain established reputation and proceed to skip thru externally controlled allowlists.

After the previous steps are completed, the public IP range can complete the Provisioning phase. The range will be created as a customized IP prefix resource in your subscription. Public IP prefixes and public IPs can be derived from your range and related to any Azure resource that supports Standard SKU Public IPs (IPs derived from a customized IP prefix can additionally be safeguarded with
DDoS Protection Standard). The IPs may not be advertised at this point and not reachable.
When ready, you can issue the command to have your range advertised from Azure and enter the Commissioning phase. The range will be marketed first from the Azure place where the customized IP prefix is located, and then by Microsoft's Wide Area Network (WAN) to the Internet. The specific region where the range was once provisioned will be posted publicly on Microsoft's IP Range GeoLocation page.
