Do you need to communicate with a device from outside your home network? Whether it is a camera or a computer, the No-IP service allows you to assign a URL to an IP, even local.

Normally, on your local network, the devices and computers connected by wire or WiFi to your box have their own IP noted like this 192.168.1.XX. The problem is that it is not possible to access these IPs from outside your network because they are only known to your box: they are local IPs.

How then to have access to a surveillance camera when you are not at home? It suffices in fact to "map" the IP of your box so that it corresponds to a domain name, for example You will then have to redirect requests from this address to the local IP to access your equipment.

How to map an IP address with No-IP?

Step 1:

On main page of the site, do Sign Up and create your account. Choose your domain name and opt for the free solution.

Activate your account by clicking on the link sent by e-mail. Make "Download Update Client" and install this small software allowing to find your IP even if the latter is dynamic. Launch the DUC and enter your credentials. From there, the domain name you have chosen will redirect to the IP of your box.


Step 2:

Now open your browser and type to access the settings of your box. After entering your subscriber identifiers, you will be able to have the list of devices connected to your box as well as their IP. Note the IP of the device you want to join. Then, the names of the settings may vary depending on the ISP boxes but go to Port translation or NAT.

Step 3:

Put the IP of your device in the destination IP as well as ports 80 externally and in destination. Choose TCP as protocol and validate. Create another translation with the same IP if you wish. From now on, the domain name you have chosen will direct to the device you have chosen. Note that the free version of No-IP allows you to map up to three IPs with different domain names.
