DENIC announced recently in a press release that .DE has the most DNSSEC-Signed second level domain names in the world .
You can read the press release after the jump :"Since 31 May 2011, the .de zone contains the public key which is suited for validation. Today, the Internet Assigned Numbers Authority (IANA) has published the related DS record in the root zone. Thus, signed .de domains can be validated as of immediately.
Already today more than 200,000 .de domains are signed with DNSSEC – i.e. the data provided by the DNS can now be checked for authenticity. This makes .de the Top Level Domain with the largest number of signed Second Level Domains worldwide.
The background to this is that DENIC offers the possibility to store authoritative data directly in the .de zone. Like the Second Level Domains delegated with own key material, these data have been signed since 31 May 2011 and can now be checked by means of a validating resolver with standard configuration. Part of this configuration is the so-called trust anchor for the root zone (https://www.iana.org/dnssec/). Configuring a trust anchor for .de in addition to the one used for the root zone still remains unnecessary and is not recommended.
Caching mechanisms in the DNS generally have the effect that new data are not visible immediately everywhere on the Internet. Operators of validating resolvers who want to validate .de domains as soon as possible may want to restart their resolver processes. This will empty the cache and accelerate the process of getting ready for validation.
With validation now available, the DNSSEC testbed infrastructure has fulfilled its purpose. As already announced, it will be continued until end of July 2011."
