Domain Name Security Extensions (DNSSEC) have been implemented in the registry of the .us top-level Internet domain.
Neustar Inc., which has operated the .us registry since 2001, received permission to apply DNSSEC in October and signed the .us zone earlier this month. The company said it will encourage domain name registrars and registrants to incorporate a digital signature via DNSSEC into their domain records in early 2010.
The .us domain, one of a number of country codes used to identify the location of an entity within its Uniform Resource Locator (URL), joins a growing number of top level domains — including .gov and .org — getting ready to secure the Internet’s Domain Name System by digitally signing DNS requests and responses.
