6to4
Debian configuration
For dynamic IP:
auto 6to4
iface 6to4 inet6 v4tunnel
address $(ipv6calc --quiet --action conv6to4 $(wget -O - 'http://ifconfig.me/ip' --quiet))
netmask 16
gateway ::192.88.99.1
endpoint 192.88.99.1
local $(wget -O - 'http://ifconfig.me/ip' --quiet)
post-up service radvd restart
post-up service shorewall6 restart
post-up echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
post-up ip -6 addr add $(ipv6calc --quiet --action conv6to4 $(wget -O - 'http://ifconfig.me/ip' --quiet))1/64 dev eth0
Traceroute to nearest IPv6 6to4 router
traceroute 192.88.99.1
Need to discuss 6to4 and link to references

there's also
ipv6calc
Uncompressed IPv6 address
Print fully uncompressed IPv6 address, w/ colons removed (useful for djbdns):
ipv6calc 2001:db8::1 --out ipv6addr --printfulluncompressed | sed 's/://g'
