Enabling DDNS (Dynamic Domain Name System) service can be beneficial in certain situations, especially if you are hosting services or devices on your home network that require remote access. DDNS allows you to assign a domain name to your dynamic IP address, making it easier to access your network from anywhere in the world.
There are several reasons why you might want to enable DDNS:
1. Remote access to your network: If you have devices or services such as a security camera, file server, or web server on your home network, enabling DDNS will allow you to access them remotely using a domain name instead of a changing IP address. This can be particularly useful if you frequently travel or if you need to access your network from different locations.
2. Hosting services: If you want to host a website, FTP server, or any other service on your home network, enabling DDNS will make it easier for others to access these services. Instead of needing to remember your IP address, they can simply use your domain name to connect.
3. Dynamic IP address: Many Internet Service Providers (ISPs) assign dynamic IP addresses to their customers, meaning that the IP address can change periodically. Enabling DDNS allows you to associate a domain name with your dynamic IP address, ensuring that you can always reach your network even if the IP address changes.
It’s important to note that not everyone needs to enable DDNS. If you don’t have any services or devices that require remote access, or if you have a static IP address from your ISP, then DDNS may not be necessary for you.
However, if you do decide to enable DDNS, it’s generally a good idea to have the updater device running at all times. This device is responsible for updating the DDNS service with your current IP address whenever it changes. Most routers and NAS servers have a built-in DDNS updating function, so it’s best to use your router as the updater device since it is the gateway to the Internet.
Enabling DDNS on your router usually involves entering your DDNS provider’s details, such as the domain name, username, and password, into your router’s settings. Once configured, the router will automatically update the DDNS service whenever your IP address changes.
Enabling DDNS can be beneficial if you need remote access to devices or services on your home network or if you have a dynamic IP address. However, it may not be necessary for everyone. Consider your specific needs and whether DDNS will provide any practical benefits before enabling it.
