aiccu for IPv6 tunnel
I don't know if IPv6 support on mobile connections is available in other countries.
In germany no mobile carrier offers IPv6 support on mobile connections while many landline providers only connect new customers via IPv6/DS-Lite protocol.
People using mobile IPv4 and landline IPv6 connections wouldnt be able to connect to their home networks from mobile without using aiccu/tunnelbrokers.
It would be great to have aiccu an my Jolla to handle those connections.
