Use Cases Here are some of the things that you can do with multiple IP addresses:. Inspect the limits with care if you plan to use lots of interfaces or IP addresses and expect to switch between different instance sizes from time to time. When you launch an instance or create an interface, a private IP address is created at the same time. You can also allocate Elastic IP addresses and associate them with the primary or secondary IP addresses of an interface. In addition to moving interfaces to other instances, you can also move secondary private IP addresses between interfaces or instances. In order to make use of multiple interfaces and IP addresses, you will need to configure your operating system accordingly.

Firstly, sockets aren't actually bound to an interface -- they're bound to an IP address. Secondly, if you want these addresses to be routable on the local network you need to use addresses on that network i. To add additional address, use the following command:. You shouldn't require any additional routing configuration since the addresses are on an existing subnet.
