Funet has been using and advertising a 6to4 relay to everywhere (openly) since late 2001. This includes the advertisement of 2002::/16 and 192.88.99.0/24. The router in question is a FreeBSD system running zebra OSPF and BGP routing protocols.

IPv6 multicast has also been tested using separate infrastructure and tunnels, but this has been shut down as of Q1/2005, pending the upgrade of the core network to support IPv6 multicast.

A TCP/UDP relay (faith in FreeBSD) is used on server-side to experimentally enable IPv6 access to a few IPv4-only services. A

An IPv6 newsfeed service is IPv6-enabled, and is generating 30+ Mbit/s of steady IPv6 traffic. Also, ftp.ipv6.funet.fi is also IPv6-operational.
