As well as IPv6 we also provide a NAT64 gateway which customers can use.
What is a NAT64 gateway
A NAT64 gateway is a service we offer that allows you to run a network that
is entirely IPv6 or mostly IPv6 - connecting to the IPv4 internet using IPv6 addresses.
It consists of two parts: A DNS resolver that provides fake responses for any host that has an IPv4 address but not an IPv6 address, and a gateway that maps those fake IPv6 addresses in to the IPv4 world.
How to use it
To use the NAT64 gateway simply set your DNS resolvers to 2001:8b0:6464::1 and 2001:8b0:6464::2. We no longer provide an IPv4 resolver due to abuse.
Does it work
Yes, it works, and even works for fragmented packets, pings, and traceroute. As you can see, this traceroute starts on an IPv6 address then goes in to the IPv4 world.
