Not my car, of course - that's a 4-cylinder boxer (maybe opoc in the future?) - but my computer infrastructure is now using IP version 6 (except a few embedded/legacy boxes which don't support it).
Changing everything over was a bit interesting; both my local ISP (Internode and the colocation operator where my servers live (Silver Server) offer IPv6 addresses but for the local ISP there were a few hoops to jump through: PPPoE for the DSL, and on top of that you need DHCPv6 to activate the IPv6 Prefix Delegation.
So far, so unspectacular - except that the state of DHCPv6 in debian is pretty lousy: the standard ISC daemon doesn't work on PPP links, full stop; the dibbler thing is reported to not do prefix delegations; the wide-dhcpv6-client is not pretty and a bit under-documented but can be made to work - and that's all the offerings.
I find it interesting that so far the spammers and the scammers don't seem to be interested in IPv6; after a week I've yet to see a single spam attempt coming from v6 addresses (my yearly average is 3 spams per minute).
