What?
Looks like alot if this is trust's between servers at many people are not signing their domains. I cannot sign mine yet because my hosting provider does not have a dnssec enabled server setup and I do not want to host my own DNS server at the moment.
Roots
Common root tlds are signed:
.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
