How to use IPv6 mapped IPv4 addresses

Status

This document is WORK IN PROGRESS.

Introduction

We offer IPv4 addresses as a service to provide you with dedicated IPv4 addresses, delivered via IPv6.
Using The ungleich NAT64 infrastructure we map an IPv4 address to a dedicated IPv6 address.

How to use the mapped IPv4 address (incoming traffic)

  • Setup the defined IPv6 address(es) on your system
    • You receive this information from the ungleich support
  • You are done

How to use the mapped IPv4 address (outgoing traffic)

  • The IPv6 prefix 2a0a:e5c0:1e:c001::/96 is provided to map the IPv4 Internet
  • You can reach f.i. 8.8.8.8 via your mapped IPv6 address with the following command:
ping 2a0a:e5c0:1e:c001::8.8.8.8

Automatic DNS mapping

TBD
