With AWS Bring Your Own IP (IPv4) , you can bring your own public IP addresses to the AWS cloud.
Datapath.io makes it easy for you to get an own block of IP addresses and have it routed to the AWS cloud. For only 170$ per month in the first year, you can rent a /24 block of 256 IP addresses from us. Buying that space at a later time is possible, too.
“AWS BYOIP is especially useful 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.”
