It is. You can configure your computer/server to be set with a particular DNS server. You can buy DNS hosts via DDNS ( DYN - Managed DNS | Email Delivery | SMTP | Domain Registration). You sign up for an account, set it up on your router, server, or a NAS system and point to the application you need.
If your IP changes for whatever reason, all you do is log onto your account on DYN and then update your public IP address and it's back up and working within 5 minutes.
