Frequently Asked Questions

Dynamic DNS (DynDNS or DDNS) is a service that assigns a fixed domain name (like yourname.dnsprovider.com) to your home internet connection. This is especially useful when your internet provider assigns you a dynamic IP address – meaning your address can change at any time, such as after a router reboot or every 24 hours.

Why does this matter for remote access?

If you’re trying to connect to your home network remotely (via VPN, remote desktop, file server, etc.), these changing IP addresses can make it difficult to reach your router reliably. DynDNS solves this problem by keeping track of your current IP and automatically updating your domain name to match.

In simple terms

Think of DynDNS like a postal forwarding service when you move — instead of sending your VPN request to an outdated address, it always forwards it to your current one. That way, you can connect to your home network even if your IP has changed, without needing to check or reconfigure anything manually.

What happens when using Dynamic DNS?

• You connect using the same hostname every time (e.g. yourname.dnsprovider.com)
• Your current IP address is updated automatically in the background
• You avoid connection issues caused by changing IPs
• Remote access becomes stable and hassle-free
