Prevalence of DNSSEC in Norway
DNSSEC (DNS Security Extensions) is a security extension to the domain name system. DNSSEC protected domains are cryptographically signed, and this makes it possible to check that the reply to a domain lookup comes from the correct source of origin, and that the lookup remains unchanged. DNSSEC was introduced for Norwegian domain names December 2014.
