FAQ
Common questions
A DNS report runs diagnostic checks on a domain’s DNS setup, evaluating nameserver configurations, mail exchanges, and record statuses for errors.
The audit checks nameserver redundancy, SOA record parameters, MX configuration validity, SPF security records, and reverse DNS mapping states.
The checker verifies that your MX records point to valid mail servers and check if security protocols like SPF are set up, helping prevent emails from bouncing or landing in spam.
A lame delegation error occurs when authoritative nameservers listed at the domain registry do not resolve records for that domain, causing access issues.
