| Since there's been so much discussion here of IPv6 here, I thought I'd mention a recent post on CircleID.com called "Examining Actual State of IPv6 Deployment": The article is by Thomas Kuehne and is a "quick-and-dirty" study he did of how many web sites were configured with AAAA records. Obviously it's not a comprehensive study, but just another data point about the readiness for IPv6 - or not. I've included the intro to the data below. Enjoy, Dan ------------ There have been quite a number of recent articles about various IPv6 issues. Thus the question: how far along is the actual IPv6 deployment? This is a quick-and-dirty survey that focuses mainly on the content provider side. What domains were surveyed? Alexa offers country depended TopSites listings. Domains listed are frequently visited by users from that country, not necessarily hosted there. The data collection is heavily biased towards sites that host files referenced from many different places (e.g. advertisement and social networks). The data collection is chiefly based on optional browser plugins and is as such frequently corrupted (e.g. for Germany mail.ru is listed ahead of rtl.de, msn.de and aol.de). How was IPv6 deployment surveyed? For each domain the domain name server was asked for IPv4(A) and IPv6(AAAA) records for the domain, www.domain, it’s mail exchanges and it’s name servers. If an IPv6 record was returned deployment was assumed. There was no check if the advised IPv6 actually provided the service. ------------ -- Dan York, CISSP, Director of Emerging Communication Technology Bring your web applications to the phone.
