Measurement Results on Deployment Ratio of Domain Authentications

WIDE antispam WG

The WIDE project signed a contract of collaborative research with JPRS and has been measuring deployment ratio of domain authentication since April 2005. JPRS gives us a list of domains under .jp and the WIDE project checks whether or not authentication information exists for each domain.

Transition on deployment ratio of domain authentication (graph)

As of May 2012, approximate deployment ratio of domain authentitaions is:

(With the "Total" below, dividing SPF and DK by MX, respectively)

How To Read

Registered
The total number of domains registered by JPRS. See the statistics provided by JPRS
MX
The total number of domains which have the MX RR
SPF
The total number of domains which have the SPF/Sender ID configuration
DK
The total number of domains which have the DKIM/DomainKeys policy.
The numeric value in parentheses is the total number of domains which have the DKIM/DomainKeys subdomain guessed by DNS response. This value includes the domains which have the DKIM/DomainKeys policy.
