Amazon Virtual Private Cloud (VPC) now allows you to bring your own publicly-routable IP address prefixes to AWS and advertise them on to the Internet. You can create Elastic IP addresses from your Bring Your Own IP (BYOIP) address prefix and use them with AWS resources such as EC2 instances, Network Load Balancers, and NAT Gateways. The Elastic IP addresses you create from BYOIP address prefix work exactly the same as Elastic IP addresses you get from Amazon. With control on advertising your BYOIP address prefixes, you can minimize your downtime during migration by simultaneously advertising your IP address prefix from AWS and withdrawing it from the current location.
If your applications are using trusted IP addresses that your partners and customers have whitelisted in their firewalls, you can now move these applications to AWS without requiring your partners and customers to change their IP address whitelists. BYOIP is also useful for applications such as commercial email services that rely on IP address reputation to allow traffic from your endpoints to reach intended recipients. Some legacy applications have hard-coded IP address dependencies. Bring Your Own IP enables you to migrate such applications to AWS with minimal disruptions.
There is no additional charge to use the BYOIP feature. Also, you don’t have to pay for Elastic IP addresses that you create from BYOIP address prefixes.
This feature is now publicly available in US East (N. Virginia), US East (Ohio) and US West (Oregon) AWS Regions. For more information about this feature, visit the Bring Your Own IP documentation.
