Presumably because they have run out of IPV4 addresses

Australia is under APNIC, which started rationing out its last /8 IP block in 2011. Australia has a decent number of allocated addresses, around 2 per capita (compare with India, with 29 addresses per 1000 persons)[1], but presumably they will have to be reclaimed from existing users. A newly started ISP in Australia could get a maximum of 2048 IPv4 addresses from APNIC. [2] If it needed more it would have to transfe…

They were talking about Austria (in Europe), not Australia :-)

In Germany, Kabel Deutschland, no longer offers ipv4. At least, My router only gets an ipv6 one. (100/6Mb + phone line = 55 eur)

How do you access IPv4 sites? Tunnel?

Some of the carriers who have gone IPv6-only like T-Mobile USA use technologies like 464XLAT to access IPv4 sites. Here's some info:

http://www.internetsociety.org/deploy360/resources/case-stud...

And RFC 6877 specifies 464XLAT:

http://tools.ietf.org/html/rfc6877

and here is even more detailed info from T-Mobile:

Regarding DS-Lite, this video from RIPE NCC provides a nice overview:

http://www.ripe.net/lir-services/training/e-learning/ipv6/tr...

Both DS-Lite and 464XLAT are ways that an ISP can be IPv6-only yet still access legacy IPv4 content and services.

I'd be very interested in knowing how these stats were calculated - 12% of the United States on IPv6 seems a bit high. Maybe what Google is saying is that "It's Available, but we're not saying people are using it." - For example, Comcast has had IPv6 widely deployed for at least a year, so most of their customer might be identified as "Available" - even if their browsers aren't doing a AAAA lookup for www.google.com.

> I'd be very interested in knowing how these stats were calculated Reasonably sure it's based off something similar to this: https://www.ietf.org/proceedings/73/slides/v6ops-4.pdf And yes, it is basically 12% of US users are capable of connecting to google over ipv6, not that they necessarily did/have. A browser might, for a URL that resolves to both v4 and v6 addresses, always try the v4 address first; this'd give…

They should all use the "Happy Eyeballs" algorithm (https://tools.ietf.org/html/rfc6555)

Every time IPv6 comes up on HN, around 50% of the comments seem to be about how IPv6 doesn't do NAT and how now every device you have is suddenly directly exposed to the internet. Let's clarify this a bit instead of answering individual commenters: In IPv6, just like in IPv4, you have a firewall. In Linux, you use ip6tables instead iptables, for example. This is what keeps your devices on your network safe. If you we…

I recently had to disable ipv6 because my router started freaking out about "neighbor table overflow". Some kind of issue between Asus and Comcast.

I've looked around and I can't find one ISP that "support" ipv6 in Sweden. The big ones alway replies with "We have enough ipv4 addresses for a long time forward, you don't have to worry." I'm not worried, I just want to have ipv6 access.

Any of the big ISPs will give you v6 access. Just phone your sales rep.

But does UPnP work on firewalls?

It does.. and it only makes sense on firewalls actually.

I'm running OpenWRT and miniupnpd to manage UPnP requests and open holes in the firewall.

I don't really think they get better connectivity. If you can establish a connection from the inside things works as intended for basically everything. Peer-to-peer is a little different. Personally I find it a little scary that we allow applications to just open up inbound ports as they see fit. Would you, say, install MySQL locally and have it listen on such an address because it's so unlikely that anyone will ever…

If you install MySQL locally, you should not have it listen on any address other than the loopback by default. And when you do expose it, if you care about security, you should configure the appropriate iptables along the way there and then, rather than relying on a magic box somewhere upstream filtering the packets. This can be doubly useful if the box in question your laptop which you carry around in various, poten…

I was just using MySQL as a hypothetical example, as they listen on all interfaces by default with packages supplied by Oracle. Next time you're on a tech conference, do a scan on the local network.

My point was that by his standard he would just let it listen on all interfaces because in his own word, nobody would find it. Which sounds very naive.
