Sign up to free Dynamic DNS forwarding
3. Unless you have a business broadband deal, it's unlikely you'll have a fixed IP address, so the address at which your router can be found over the Internet will change from time to time. This makes it impossible to guarantee that anyone wanting to access your webcam would be able to locate it using the same details each time.
Dynamic DNS services, like that provided by dyn.com, maintain a database of changing IP addresses, assigning you a subdomain that forwards to your home broadband connection, allowing you to remotely access your IP camera.
Point your browser at and click Get It Now to start the sign-up process. Choose a hostname, leave the service set to Host with IP Address and click the link containing your IP address to auto-populate the field above it.
Click Add to Cart, then provide a password and email address for the confirmation message. dyn.com will send you a message containing a link which, when clicked, will let you complete the setup process and activate your chosen hostname.
Set up your router
4. Although your hostname - catfoodcam.dyndns.org in our case - will now point towards your home broadband connection, it might not be accurate in the future if your ISP-provided dynamically-assigned address changes. You therefore need to set your router to keep the remote database at dyndns.org updated with any changes it detects.
Open your router configuration pages by typing its address into your browser (find this on Windows by opening Control Panel and clicking Control Panel > Network and Internet > View Network Status and Tasks > Local area connection (under Active Networks) > Details. On the Mac go to System Preferences > Network > Advanced > TCP/IP).
5. Every router's configuration pages will differ slightly, so check the main section headings for either Dynamic DNS or DDNS. Enter the required details, which will likely consist of your chosen hostname, plus your DNS service login details. This will allow your router to write its ISP-assigned address to your subdomain's record each time it changes.
6. You now need to re-route any incoming Web traffic arriving at your router to your IP camera. You should already know its address on your network as you will have configured it through your browser, but if you can't recall what this was, check your router's list of connected clients or attached devices and make a note of its IP address. On our network, the devices at 192.168.1.15 and 192.168.1.13 are our front door and kitchen cameras respectively.
