[Editor's Note: This story is taken from information issued by Cloudflare and it refers to their experiences of IPv6. However, it remains a useful indicator on IPv6 availability and usage. Have a healthy pinch of salt to hand.]

It's 2016 and almost every site using Cloudflare (more than 4 million of them) is using IPv6. Because of this, Cloudflare sees significant IPv6 traffic globally where networks have enabled IPv6 to the consumer.

IPv6 is faster for two reasons. The first is that many major operating systems and browsers like iOS, MacOS, Chrome and Firefox impose anywhere from a 25ms to 300ms artificial delay on connections made over IPv4. The second is that some mobile networks won't need to perform extra v4 -> v6 and v6 -> v4 translations to connect visitors to IPv6 enabled sites if the phone is only assigned an IPv6 address. (IPv6-only phones are becoming very common. If you have a phone on T-Mobile, Telstra, SK Telecom, Orange, or EE UK, to name a few, it's likely you're v6-only.)

How much faster is IPv6? Our data shows that visitors connecting over IPv6 were able to connect and load pages in 27% less time than visitors connecting over IPv4. LinkedIn found an even more dramatic effect, with up to a 40% performance boost on mobile connections over IPv6. Facebook also found a significant performance increase, around 10-15% on IPv6.

IPv6 is clearly important for driving a faster, better internet, so who is driving IPv6 adoption?

In terms of countries, Belgium leads by a mile. Over the last 30 days, 56.47% of traffic (in bytes) to Belgians on Cloudflare has been over IPv6. This is largely due to Telenet, an ISP in Belgium, doing almost 96.8% of their traffic over IPv6!

The Irish numbers are artificially high due to several of Facebook's IPv6 ranges being registered in Ireland. Facebook does an enormous amount of traffic over IPv6 –– 81% of Facebook's traffic through Cloudflare is IPv6. In fact, Facebook's crawling over IPv6 actually accounts for 6.9% of Cloudflare's total outbound IPv6 traffic.

    I really don't want my entire LAN visible to the world. I can't see how sensible people would want that security-wise.

    I use NAT nowadays to obscure which and how many computers I have running behind the web facing router. Additionally, as IPv4/6 has gotten more commoditized, targetted by attacks, and generally FUBAR, I have simply shifted my services to darknet web services. The darknets have become the refuge for people who enjoyed 80s and 90s era internet, with the bonus of free addresses and in the case of I2P domain names. Related and interesting: it appears google and a number of other services are spidering darknet sites (whether directly, or via reverse proxies is unknown.) The only benefit is Tor, I2P, cjdns and others already act like Cloudflare's proxy services, dynamically generating ip addresses in whatever range, IPv4 or v6 that you need to connect to. The future of internet services should be protocol agnostic, with the 'service' layer resembling p2p/darknet browsing services, double both as a way to segregate service types as well as reducing costs associating with maintaining what should be 'free' infrastructure services, like domain names and address blocks, the costs of which are a profitable relic of an era where the operating costs required to maintain and administer it made SOME sense. But since the internet exploded in popularity it has simply become a cash cow for those who could latch on. Look no further than GoDaddy and Verisign on the domain/encryption side.
