DynamicIP + DynDNS works just as fine. Getting DynDNS can be acomplished via many routes. - Even old routers support at least noip.com and update the IP when it changes - major DynDNS providers have a custom tool you can install, running in the background sending the current IP every minute or so - every major registrar has a DNS API, which allows you to send IP updates in a simple CURL command and putting that command into crontab automates this as well.
