Hi,
We are planning to have an application run on Amazon's cloud which requires a static IP for it to work. However it appears from Amazon's documentation that static IPs are NOT allowed...

The machine's external IP address is essentially a static address. You will have it until your instance is terminated or until Amazon needs to renumber its network. This could be months or years from now, which in this day and age, is about as static as it gets.

8.12. Can I use a static IP in my instances?
No. Your image must be configured as a DHCP client and it will be assigned an IP.
This however confused me a little bit: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1346 --> Introduction
Elastic IP addresses are static IP addresses designed for dynamic cloud computing. An Elastic IP address is associated with your account, not a particular instance, and you control that address until you choose to explicitly release it. Unlike traditional static IP addresses, however, Elastic IP addresses allow you to mask instance or availability zone failures by programmatically remapping your public IP addresses to any instance associated with your account. Rather than waiting on a data technician to reconfigure or replace your host, or waiting for DNS to propagate to all of your customers, Amazon EC2 enables you to engineer around problems with your instance or software by programmatically remapping your Elastic IP address to a replacement instance.
Is there any way that a machine instance can have a static IP address linked to it?
