So, you can’t use DDNS if you use somebody else’s IP. You need to have direct access to your home network’s WAN IP address if you want to dial home.
To take advantage of DDNS, you need three things: A private WAN IP, a Dynamic DNS service, and a DDNS updater device. That’s where DDNS comes into play: It associates your current WAN IP address - no matter what it is at any given time - with a consistent domain name of your choice.Īs a result, you can always use that label (domain name) to access your home network from anywhere in the world without even having to know its IP address. That address might have moved to somebody else’s home network when you do. In other words, even if you write down your current WAN IP address - or remember it by heart - you probably can’t rely on it to dial home. In a week, though, check again, and chances are you’ll get a new address. You can easily find out your WAN IP right now. The majority of home broadband plans don’t include a static WAN IP - it’s expensive to have a fixed WAN IP address that remains the same at all times. (This is similar to your phone’s Contacts, where you only need to remember your friends’ names and not their digits.)ĭynamic DNS is the same concept but applies to a periodically changing or “dynamic” WAN IP. You can find out more about DNS in this post, but, in a nutshell, DNS is a mechanism that associates a label - such as a domain name like - with an IP address.ĭNS is helpful because it’s much easier for us to remember a label than a string of numbers. To know what DDNS is, you first need to understand DNS - short for domain name system.
