A little bit of NAT64 and a little bit of magic
---
body:

In the [second ungleich tech
talk](https://www.youtube.com/watch?v=Gfe35IFdx-Q) you can find out
how to access IPv4 only devices from the IPv6 Internet using a simple
NAT64 translator.

This is especially helpful if you are by default in IPv6 only
networks, but you still have legacy-only networks or legacy-only
devices that you need to access.

In this ungleich tech talk we use the
[VIWIB](/u/products/viwib-wifi-ipv6-box/) as a NAT64 translator and
a reconfigured [VIGIR](/u/products/vigir/) as an IPv4 only demo
device.
