DNS Lookup Guide
RookDNS lists common record types in one view so you can debug mail and hosting without a desktop dig install.
RookDNS resolves a domain and prints each record type on its own row. SPF (v=spf1) and DMARC (_dmarc TXT) are highlighted because they are the usual email-auth questions.
SPF and DMARC
SPF authorizes sending hosts. DMARC tells receivers how to handle alignment failures. Both are TXT records; long SPF strings may need flattening at your DNS host.
MX and mail routing
MX records show which servers accept mail and their priority. Pair MX checks with the SMTP tester when debugging submission versus inbound DNS.
DNSSEC
DS and DNSKEY rows indicate DNSSEC material in the zone. A full validation path still depends on your resolver; this page lists what is published.
