How to set-up the Proximus b-box to keep my dyn-ip up-to-date?

With a normal Proximus internet connection, your IP-address changes regularly. But the standard Proximus router (b-box) does offer a way to keep your dyn-ip up-to-date.

The first step is to create the dyn-ip record in our system. In this example we purposefully used the wrong IP-address to start with. That way we can later on verify if the b-box has indeed updated the address.

Create zone for dyn-ip


On your b-box, go to "My Modem" and then click on "DynDNS". Set this up as follows:
  • Enable: On
  • Provider: Custom
  • User name: Enter the complete host name. In our example this is dyn.yourname.be
  • Password: The password you have chosen when creating the dyn-ip on our webinterface
  • Host name: Again the host name
  • Server: www.bnamed.net
  • Port: 80
  • Request: http://www.bnamed.net/dyn/dyn.asp
  • Authentication: Basic

Save the settings by clicking "OK". If you then restart your modem, you should receive a new IP-address and you'll be able to verify if the dyn-ip indeed gets updated (it can take one or two minutes after the restart before you'll be able to verify that the dyn-ip has been updated).
