title: Static IP for Auto Scale in AWS
body: <p>I need all of my instances in AWS auto scaling group to be configured with (known) static IP's. I will be whitelisting all of these IPs in a mail server later (that's why need all of them to be static). Is it possible using the regular cloudformation approach? May be assigning a second NIC and assigning it an IP from a static IP range? Any ideas?</p>
