Only non-routable (private) IPv4 addresses are used on the home networks. This triggers the use of translators of various kinds. That the core only runs IPv6 complicates the matter further, but not beyond what can be maintained and run.

The components for IPv6 to IPv4 are:

• Translating IP directly (NAT-PT), and copying the user’s data from one connection to another (FAITH). Cooperation with the totd DNS proxy is needed to get the connections needing translation to the translators.

• TRT (Transport Relay Translator) and one-to-one translation (6tunnel).

• Application specific solutions (for FTP).
