• Many thanks to all people involved in monitoring IPv6 and making these numbers public

• The presented sites are my own selection but there are many others

• Looking at future?

Interviews

Monitoring ‘precursors’ (IPv6 prefixes, devices, ...)

• Looking at current state of the Internet

Open metrics => open results

Worldwide view

4Cisco Public, all rights reserved 2014

• Regional Internet Registries (RIPE, ARIN, ...)

Which ISP has IPv4 and IPv6 prefixes (precursor)

• Internet routing tables (routeview, ...)

Which ISP has at least an IPv6 router

• Traffic seen from this prefix

Using techniques described later

This is alive prefixes

• Measure the web traffic

Using a small web bug (1x1 pixel transparent GIF)

Used by Google, and others

Can precisely measure IPv4, IPv6 and dual-stack

E.g. http://www.vyncke.org/countv6/

Web servers log files

Easier but cannot check IPv4, IPv6

Google Ads

Used by APnic

All ads are in flash and flash can try to download IPv4, IPv6, dual-stack and report

• Participate in dual-stack peer-to-peer networks such as BitTorrent

10Cisco Public, all rights reserved 2014

• By inserting a 1x1 pixel transparent image (or IFRAME)

Or even better 3 images:

IPv4-only

IPv6-only

Dual-stack then check whether IPv4 or IPv6 was preferred

• IPv6 brokenness (old 6to4 CPE mainly): can reach IPv4-only but not dual-stack (because IPv6 was preferred but broken), cfr Tore Anderson’s experiment

• IPv6 non-managed tunnels (Sixxs, Gogonet, Hurricane Electric) because the AS is different between IPv4 and IPv6

• Can generate a lot of data and CPU load => sampling on large sites

• Simple and easy

• Try to connect to www.example.org over IPv6

Make a AAAA DNS request

Then try to connect to it by TCP on port 80

• But, also try www6.example.org IPv6.example.org, ...

This is an indicator of ‘IPv6 under test’ or ‘IPv6 pilot’

• Can be extended to measure email and DNS servers of a domain

• List of most visited web sites• Freely available top-1-million

== Which are popular sites visited by the whole Internet

Then class by country top level domain: .be, .ch, .lu

Issues:

www.ice-watch.com is actually in Belgium

www.youtu.be is actually outside of Belgium

Estimation of IPv6-readiness of a country

• Paying list of visited web sites by country== Which are popular sites actually visited by users of this country

E.g. google.ch, facebook.com, google.com, live.com, ...

Assuming a long-tail distribution, can estimate the amount of IPv6 traffic IF all subscribers were dual-stack

• Getting a 100 score based on

% IPv6 enabled transit AS : 25 %

Geometric mean of (content, user): 75%

• Getting a relative index based on content/user/transit relative position with 10 if a country is the top performer in each metric

• Note: this weighting has recently changed....

• BitTorrent is a dual-stack peer-to-peer file exchange

Some trackers have dual-stack peer lists

Private Exchange is also dual-stack

Distributed Hash Table does not appear to be dual-stack

• Of course, only pretend to have the file, do not upload/download it

• Another way to measure user deployments: BitTorrent

• Trackers can have IPv6 peers

• Direct peer exchange
