Can public IP's that are assigned to a computer be made static?
We have a secure web site that verifies the IP address of the computer before it can authenticate to the web site. Today two of our computers that previously had public IP addresses got new ones. Today they had 50.97.211.199. Previously they had 50.97.211.194. These are from Softlayer.com. How do we stop them from changing?

Yes, you can request static public ip's from your isp, they normally cost extra than dynamic ip addresses which are essentially taken from a pool of addresses. Is it that you are authenticating already known users such as employees access, if so maybe mac address might be a simpler authentication method, if i am reading your question correctly
PS I just re-read your question. Of course - if the authentication is IP based, only option 1 apples - as dmwynne agrees, you NEED static IPs.
That's it. You can't stop them from changing, if they're dynamic.
If the ISP changed them, and they were supposed to be static - you need to fire those dudes.

Thanks to all of you for agreeing. :-)
The alternatives are:
- Go with an ISP who DOES provide static IPs (if Softlayer don't)...
- Use Dynamic DNS. no-ip.com are a good example. Basically, define what you want your domain to be called, and that's it. You then download a small tray app (that you can also optionally run as a service). When your server starts, it reports back to the dynamic DNS provider what its current IP is, thus 'gluing' the current IP, whatever it happens to be, to the chosen domain name.
Capiche?
Good! x
