I'm new to linode. What is their outgoing bandwidth policy?

I mean, is it possible to automatically set up a throttle, to avoid charges when going over 2TB? (or do I have to fiddle with iptables to find a way to do that).

Also, do you know if it's possible to get a /48 IPv6?

On https://library.linode.com/networking/ipv6 they only mention /56

I'd hate to run a HE tunnelbroker just because they don't support that :-/ (I love HE.net and tunnelbroker.net, but it would just be wasteful)

EDIT: /48 make running multiple VPNs very easy - that's lazy, but IPv6 are not scarce resources!

EDIT2: just got an answer - they can't do /48 :-(
