I need a public IP Address that should never change.

So far I found the following:

  • Amazon EC2 Elastic IP Addresses
  • Hetzner Failover-IPs can be reassigned to a different Hardware

How sure can I be they never change? Or are there better solutions?

I'm sure there are better solutions. What's the problem? What is the problem that you are expecting a public IP address that never changes to solve? –  David Schwartz Sep 13 '12 at 6:45
    
Simple, USE DNS, and don't worry about a fixed IP. –  Zoredache Sep 13 '12 at 7:07
    
@Zoredache: Not that simple - what about firewalls and access-lists? But your workflows and documentations should always be prepared for changing IP adresses. At the latest with IPv6... :*) –  Michuelnik Sep 13 '12 at 7:19

You left one option out: Go to your ISP and ask them for a fixed IP address or for a IP range. Any ISP should be able to do that. Even those who do not list it in obvious places on their web pages.

How sure can I be they never change?

Easy. Get your own range. This is how the internet worked for ages.

Or are there better solutions?

I think a fixed name is more important than a fixed IP. Which means DNS.
Is there any reason why you need a fixed IP over a fixed name?
