check_domain
shallownet.isitdns/isitdns · Verify this server
The eleven-check DNS audit for a domain: parent and child nameservers agree, no open recursion, DNSSEC chain, TTL sanity, mail posture, glue at the parent, a DS that matches a live DNSKEY, and whether a truncated UDP answer can be had over TCP. Every check reports ok, warn, fail or skipped with the reason. THERE IS NO SCORE AND NO LETTER GRADE: the checks state what they found and the caller decides what it means. Six of the eleven belong to a ZONE rather than to a name (the delegation, the DNSSEC chain, the nameserver's recursion policy, the glue, the DS match and the TCP fallback), so if you ask about a hostname those six are evaluated for the enclosing zone: the answer names it and marks the rows it applies to.
