A DNS lookup is a query to the Domain Name System that returns the records tied to a domain — its IP addresses (A/AAAA), mail servers (MX), nameservers (NS), and text records like SPF and DMARC. Secably's DNS lookup checks every record type, validates email security, and is free with no signup.
The Domain Name System is the internet's address book: it translates human-readable names like example.com into the IP addresses machines actually use, and stores the records that route your email, prove domain ownership, and protect against spoofing. A DNS lookup queries that system and returns every record a domain publishes.
Reading those records tells you where a domain points, which servers handle its mail, and whether its email and DNS security are configured correctly — all from public data, without touching the server itself.
Misconfigured DNS is a quiet but serious risk. A missing or weak SPF/DMARC policy lets attackers send phishing email that appears to come from your domain. A dangling record pointing at a de-provisioned service invites a subdomain takeover. And a domain that allows zone transfers can hand an attacker its entire internal map in one request.
Checking your DNS regularly catches these before they're exploited — and confirms that changes (a migration, a new mail provider) actually took effect.
Secably queries the domain's authoritative nameservers for every record type, then analyzes the results for email and DNS security issues.
Retrieves A, AAAA, MX, NS, TXT, SOA, CNAME, and CAA records so you see everything the domain publishes in one view.
Parses your SPF and DMARC policies and flags weak or missing configuration that would let others spoof your domain in email.
Checks whether DNSSEC is enabled to prevent spoofing, and tests whether the domain leaks its full zone via an AXFR transfer.
Type a domain like example.com. No record type to pick — Secably fetches them all.
Secably queries the authoritative nameservers and analyzes email and DNS security in one pass.
Every record is grouped by type, with SPF/DMARC/DNSSEC flags highlighted. Save or export the report with a free account.
