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
