My personal site's IP address has changed a ton over the last 5 years, but the domain name has been able to stay the same. So anyone who knows my site can always find it at the same place. That seems like a valuable service which I would like to keep. Maybe what the author really wants is a cheap or free TLD that gives out uuids instead of human readable domain names? Or as they sort of touch on it could be subdomain based? I think having a layer between address and IP helps a lot vs using "raw" ip addresses...
