The following sites provide ongoing statistics about the adoption of DNSSEC:
- ICANN TLD DNSSEC Report
- US Government DNSSEC Deployment Status
- US NIST IPv6 and DNSSEC Statistics – excellent set of charts and lists related to IPv6 and DNSSEC deployment within the US government as well as estimates for industry and universities.
- Verisign Labs Scoreboard - note the graphs of counts and percentages found on the page.
University projects:
- SecSpider the DNSSEC Monitoring Project
Note: Verisign Labs also maintains a SecSpider site, but it is not clear from the site when the last update date was.
Additionally, on October 4, 2011, the United Kingdom’s OFCOM published a survey of UK DNSSEC usage that provided useful statistics not only for the UK but also for Europe.
