It's being implied everywhere that native IPv6 is somehow important to seek, since we're running out of IPv4 addresses.
Ok, so I'll give you that tunneling a really short bit, tunneling isn't too bad, but native is most of the time better.
5+ years back we used to run 6bone for out IPv6 connectivity. It was hugely broken. As soon as we started running native ipv6 in the core and started peering natively, quality improved hugely.
So yes, 6RD or alike where tunneling is done locally within the ISP or very close to it, is a valid deployment scenario, but middle/long term, native is better.
And IPv6 is not a short term fix for IPv4 address runout, it's a long term solution for it. As humankind, we just failed to get it deployed in time for the long term solution to be widely available before we ran out of IPv4 addresses.
