The VIIRB connects
anything anywhere
with IPv6

Our mission

We want to enable anyone, anyone with IPv6. It should be as simple as "plug and play". We are very proud to announce that with the VPN IPv6 IoT Router Box (VIIRB), we can now offer exactly this.

How it works

The VIIRB is pre-configured with a Wireguard VPN. With this VPN you will receive a /48 IPv6 prefix. The IPv6 connectivity is provided by Data Center Light.

When you plug in the ethernet cable and power it on, it will do the following:

  • Establish a VPN connection via IPv4 or IPv6 to Data Center Light
  • Announce a pre-configured /64 network on the LAN

By default the firewall is configured to allow outgoing connections from LAN towards the VPN. Incoming ICMP6, SSH, HTTP and HTTPS are open by default.

Fully Open

The VIIRB is running stock OpenWRT. We flash the latest available version before shipping. SSH and http access to the OpenWRT management is open. The password is randomly generated and will be sent to you with the shipping confirmation.

VIIRB use cases

So what can you do with the VIIRB?

1. IPv6 on the go

Going to a friend and the network does not have IPv6? Just bring your VIIRB, plug it in and enjoy a fully enabled IPv6 network.

2. IPv6 world wide reachable audio system

You can install the music player daemon on the VIIRB and allow remote control of the music from anywhere in the world. You can either put your music locally on an SDXC card or you can even mount your music collection or stream music to it.

Just connect the VIIRB to your audio system, configure it and enjoy remotely controlled music!

3. A BGP router

With bird2 and quagga available on OpenWRT, you can use it directly for peering with other ASNs.

In fact, if you let us know before ordering, we can even connect your VIIRB to a VPN endpoint that allows peering with the real Internet.

4. A hacking box

Thi VIIRB contains a variety of additional features like PWM, GPIO, A/D converter, D/A converter and so on. It can also plug in a small camera, so you can turn it into an IPv6 enabled camera. The VIIRB is so universal, easy and hackable that it's just fun to use it.

Remote controlling your lights, your blinds, your doorbell - all remotely via IPv6? You can do it with the VIIRB!

In our long term tests the WiFi of the VIIRB shows reliability issues with clients that are not directly next to it.

As the majority of VIIRB users we are in touch with did not use the WiFi and our preference is on delivering stable systems, we have turned the WiFi off by default. Effective since 2020-12-01.

If you are looking for an IPv6 enabler with reliable WiFi, we recommend to use the VIWIB instead.

What is in the box

When you order the VIIRB, you will receive one pre-configured system. The box does not contain the micro usb cable or a charger, because we think that most people already have this and we don't want to contribute to tech waste.

IPv6VPN included

A free subscription for 1 year is included. This way you can plug in the VIIRB and just get started with IPv6.


The VIIRB comes with a variety of possible add-ons that can turn it into an even more versatile device.

Turning the VIIRB into an IPv6 camera

You can turn the VIIRB into an IPv6 streaming camera with a compatible USB-Webcam. For 25 CHF you can add a tested, Full HD (1920x1080) USB camera to your VIIRB order.

Turning the VIIRB into an IPv6 thermometer

If you want to know how hot (or cold) it is, you can use an USB temperature sensor to measure the temperature. For 20 CHF you can add a tested temperature sensor to your VIIRB order.

Turning the VIIRB into an LTE/4G router

Using an USB 4G Modem you can use the VIIRB to enable a network not only with IPv6, but also with Internet connectivity in general.

For 75 CHF you can add a 4G modem to your VIIRB order.

Turning the VIIRB into a GPS tracker

The VIIRB is small and universal. What if you could use it to track things? Like your car, your bike, your boat? And check where your things are using IPv6?

You can add the USB GPS tracker add on for 25 CHF as a single device.

Multiple Add-Ons via USB Hub

To connect more than one add-on to the VIIRB, you will need a USB-Hub. For 25 CHF you can add a verified, 4 Port USB hub to your VIIRB order.

The VIIRB autonomous security system

The VIIRB can be turned into an autonomous security system with the following add-ons:

  • USB Hub (to support multiple add-ons)
  • LTE/4G Router (Internet Uplink, excluding SIM card)
  • GPS Tracker (To record where the VIIRB is)
  • USB Camera (To stream what the VIIRB can see)

The autonomous security system set can be added to your VIIRB order for 150 CHF (223 CHF including the VIIRB).



Update 2023-02-04:VIIRB is discontiued.

Thank you for the love, our VIIRB is sold out and discontinued. If you missed to order a VIIRB we have VIWIB, a mini router box with a reliable WiFi option, you can check out VIWIB or VIGIR.

VIIRB in the Media

More of it

You can also announce your own IPv6 space via the VIIRB. The only requirement is that you have an ASN and an IPv6 prefix. Checkout the BGP Peering for more details.

How it works in detail

The complete flow for how your computers get IPv6 in the LAN is show in the following picture:

So basically the VIIRB...

  • gets an IPv4 address in your LAN
  • connects to the service
  • Gets its /48 routed via Wireguard
  • Announces (via Router Advertisements) IPv6 on the LAN
  • Because of the announcement, all clients in the LAN assign themself an IPv6 address
