What is DDNS and how does it work? (Explained for beginners) or Can someone explain what is DDNS in s

Wow, thanks for all the replies! You guys made what is ddns way clearer than the articles I found.

I tried setting up No-IP on my router, and it actually worked! Now I can access my security cam without freaking out about IP changes.

Quick follow-up: Does DDNS slow down your connection at all? Or is it just a background thing?

Also, DuckDNS looks even simpler—might give that a shot next. Appreciate the help! 😊
