Generally available: Custom IP Prefixes (BYOIP) now available in US Government regions

Published date: October 25, 2022

The ability to bring your own public IP ranges is now available in all US Government regions.


  • You can now bring your own IPv6 ranges to Azure. These ranges must be a /48 size and can be split into multiple regional /64 ranges, of which a subset of IPs can be used as Public IP Prefixes.
  • A regional commissioning feature now allows you to advertise a range internally within an Azure region prior to full global advertisement to the Internet, easing the migration process for a range that is already live outside of Azure.
