I recommend 2 degrees broadband. Really great service (both technically
and customer service). They also allow you to host ip6.arpa records, so
you can have reverse delegation on the IPv6 address block. Works with
both xDSL and UFB connections.
I���d second that. We have been with 2degrees, previously Snap, for some years and been very satisfied with them. Add to this discounts for being 2degrees mobile customers and Super Gold Card holders (when did that happen).
It���s disappointing that so many NZ ISP���s are dragging the chain on IPv6. We participated in the Worldxchange IPv6 trial which started over 10 years ago and was then closed to new applicants.
Top level exhaustion of IPv4 addresses happened over seven years ago and IPv6 technology has been fully operational in pretty much every piece of modern CPE equipment for years.
For me IPv6 is a must have and in my view any serious participant in the industry should be well advanced with deployment by now. Removing support is tragic and reprehensible.
