Nameservers, website, email and security records checked the way the rest of the internet sees them, straight from the registry and each of your nameservers. Every problem comes with what it means and how to fix it.
What it checks
Over 30 checks, from the registry down to the records that keep your email out of spam.
What the registry holds, glue, whether every nameserver answers with authority, agrees with the others and sits on separate networks.
The bare domain and www, IPv6, reverse DNS, and addresses that only work inside one network.
MX records, mail server addresses and reverse DNS, SPF (with its 10 look-up limit), DMARC and DKIM.
DNSSEC, including when it's half set up or broken, open resolvers, and CAA for SSL certificates.
