Amazon Virtual Private Cloud (VPC) now supports BYOIP and BYOASN in all AWS Local Zones

Starting today, Amazon VPC supports two key public IP address management features, Bring-Your-Own-IP (BYOIP) and Bring-Your-Own-ASN (BYOASN), in all AWS Local Zones. If your applications use trusted IP addresses and Autonomous System Numbers (ASNs) that your customers or partners have allowed in their networks, you can run these applications in AWS Local Zones without requiring your partners or customers to change their allow-lists.

The reachability of many workloads, including host-managed VPNs, proxies, and telecommunication network functions, depends on an organization’s IP address and ASN. With BYOIP, you can now assign your public IPs to workloads in AWS Local Zones, and with BYOASN, you can advertise them using your own ASN. This ensures your workloads remain reachable by customers or partners that have allowlisted your IP addresses and ASN.

The BYOIP and BYOASN features are available in all AWS Local Zones, and all AWS Regions except China (Beijing, operated by Sinnet) and China (Ningxia, operated by NWCD).

For more information about this feature, review the EC2 BYOIP documentation and IPAM tutorials.
