DNSSEC

Roots

Delegation of Signing (DS) records contain the digital signature information for your domain name's DNS. In the Domain Manager, you can manage DS records for the following domain name extensions:

   .com
   .net
   .biz
   .us
   .org
   .eu
   .co.uk, .me.uk, and .org.uk
   .co, .com.co, .net.co, and .nom.co

Domains

dig @dnsserver domain.tld +dnssec

No authoritative dnssec response means no DNSSEC employed at domain. You will see the keys.

IE

google.com has no DNSSEC on the domain
