Short answer: Yep, dynamic dns means your domain always points to your current IP.
Longer answer: You sign up with a DDNS provider (like DynDNS or afraid.org), and they give you a subdomain. Their client software runs on your network and pings their server every time your IP changes.
Some routers even have this built-in. As for safety, it’s as safe as what you’re exposing—don’t open ports recklessly!
