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

what is ddns? Short answer: It makes your changing IP act like a static one.

Longer answer: Your ISP probably doesn’t give you a fixed IP (that’s expensive). So when your IP refreshes, DDNS updates your domain automatically.

Use cases:
- Accessing your NAS from anywhere
- Running a personal VPN
- Avoiding "hey bro, what’s your new IP?" texts

Providers: No-IP (free tier), or Cloudflare if you’re fancy.
