US company VeriSign announced the roll-out schedule for the authentication of.com and.net domains. From the 9th of December, users will be able to protect their own.com domains with DNSSEC signatures shortly afterwards. This is mainly designed to prevent future cache-poisoning attacks. 60 out of 294 Top Level Domains are currently offering DNSSec signatures, while 44 have deposited their keys in the root zone. The co-existence of multiple TLD key deposits is currently still being discussed.”]
