What is DynDNS?
DynDNS (Dynamic Domain Name System) is a service that allows you to link a dynamic IP address to a fixed domain name.
This means that even if your IP address changes frequently, the domain name will always point to the correct address.
This is especially useful when you need remote access to services that rely on a constantly changing IP address.
What Can I Use the DynDNS Service For?
1. Remote Access to Your Home Network
With DynDNS, you can access your home network anytime, anywhere — whether it's for remote maintenance, file sharing, or managing devices like IP cameras, NAS systems, or servers. Instead of keeping track of your changing IP address, you can use a fixed domain name that always points to the correct IP.
2. Remote Access to Servers
If you're running your own web, email, or FTP server, DynDNS ensures that your servers remain accessible even if your router's public IP address changes. This allows you to access your server remotely from any location without worrying about IP changes.
3. IP Surveillance and Security Systems
DynDNS is ideal for remote monitoring of security cameras or alarm systems installed at your home or office. With a fixed domain name, you can access your security system at any time, without having to deal with changing IP addresses.
4. Access to Network Devices (NAS, Printers, Smart Home)
If you have network devices like a NAS (Network Attached Storage) or smart home systems, DynDNS allows you to access them remotely. The domain name ensures your devices are always reachable, even if your ISP assigns you a dynamic IP address.
5. Hosting Game Servers for Friends and Players
DynDNS is also useful for hosting private game servers. You can replace your IP address with an easy-to-remember domain name, allowing your friends and players to connect to your server without having to constantly ask for your current IP address.
6. Setting Up a VPN Server
If you want to set up a VPN (Virtual Private Network) to securely access your home network or workplace, DynDNS ensures that the VPN server is always reachable via a consistent domain name, even if your IP address changes.
How Does DynDNS Work?
Every time the IP address of your internet connection changes, your network device (e.g., your Fritz!Box or Synology NAS) notifies our DynDNS service of the newly assigned IP address.
Your DynDNS host, which you use with us, will then automatically switch to the new IP address, and the DNS record of your domain will be updated. The update happens automatically and almost in real time.
In Summary:
DynDNS is a valuable tool when you need access to services that depend on a dynamic IP address.
Whether for remote access to your home network, hosting a server, or using surveillance systems, DynDNS ensures you always have the correct access point to your network, without having to deal with changing IP addresses.
