Using the Custom IP Prefix resource, you can now bring your own public IPv4 ranges to Azure and use them like any other Azure-owned public IP ranges. Once onboarded, these IPs can be associated with Azure resources, interact with private IPs and VNETs within Azure’s network, and reach external destinations by egressing from Microsoft’s Wide Area Network.

In order to bring a public IP range to use on Azure, you must own and have registered the range with a Routing Internet Registry such as ARIN or RIPE. ([View Highlight] (https://read.readwise.io/read/01hww01zksvey4wq80drje24e5))
