DDNS (Dynamic DNS) is basically a way to keep your domain name pointing to your home IP even when it changes.
Think of it like this: your home IP is like a phone number that keeps changing, but DDNS is like an auto-updating phonebook. So instead of telling people "Hey, my new IP is 123.456.789," DDNS does it for you automatically.
Why would you need it? Well, if you wanna access your home server, security cameras, or game server from outside, DDNS makes it way easier.
Some free DDNS services: No-IP, DuckDNS. Super easy to set up!
