The objetive?•Again: If our wives had a computer
with only IPv6 connectivity, what would they see?
•N.B.: Our wives are lawyers and they manage to live without computer skills
(FYI: at IETF-71 in Philadelphia there will be a 30-60 min. “use-ipv6-only” test to see if there’s ipv6 life out there. Good luck...)

Why?• Everybody says IPv4 address
space is depleted (now seems to be serious stuff)
• Everybody says “we have to deploy IPv6”
• But... there is such a thing as real life in IPv6 ?
• Is IPv6 really useful for something more than theoretical discussions or just small talk?

Investigative method
• No rocket science here
• Just plain lookups in DNS space, some easy-to-do tests
• Plus some web and mail digging
• No traffic analysis here

Investigative method (2)• Go get the most visited webs per country
Source: http://www.alexa.com/
• And then:
- Ask the DNS of that domain for...
- an AAAA DNS entry for the web service and the email (MX), a DNS server with an IPv6 address

• If there is a IPv6 entry in the DNS, verify that it works following three steps:
- Open the web page with an IPv6 navigator
- Telnet to port 25 and do some basic SMTP dialog
- Dig to the IPv6 DNS server

• Give ipv6 a chance...
• Though you can associate A and AAAA records to www.example.com, many domains do it by different ways:
- www.ipv6.example.com
- www6.example.com
- ipv6.example.com
Periodic scan results are available at:

•We also do a small check on the DNS hierarchy
• Root servers with AAAA addressing
• TLD (gTLD and ccTLD) with AAAA addresing
(to be increasingly automated by some scripts...)

facts from top 500/100 lists
• (ipv6)Microsoft present (and unreachable) everywere
• (ipv6)hp.com still there (and unreachable), but in much less countries
• (ipv6)elmundo.es has stopped providing service, although the name still solved to AAAA
• Less (overall) ipv6 www sites found at this round:
• of 103 countries, 69 have the same number of sites (most of them compatible with 0), 21 have less, and 13 more than in previous edition.

facts from top 500/100 lists (ii)
• Some “real” sites disappeared, some new came out, and also some “incorrect” sites went out.
• The general balance keeps being slightly positive (+0.001% ipv6 to ipv4 ratio) for the real sites.
• Still no significative tracks of ipv6 real services in the commercial web environment.
