What we check

Delegation

Does the registry point to the right nameservers, and do they have working IP addresses?

Nameservers

Do all your nameservers answer, agree with each other and run on separate networks?

SOA record

Are the serial number and refresh timers set the way other DNS servers expect?

Mail (MX)

Can other mail servers find where to deliver e-mail for your domain?

SPF, DKIM and DMARC

Is your domain protected against people sending e-mail in your name?

DNSSEC and CAA

Are your DNS answers signed, and who may issue SSL certificates for your domain?
