DNS Lookup
Site HealthTestedDNS records, email authentication (SPF/DKIM/DMARC), nameservers, and domain configuration.
DNS records are the backbone of your domain's infrastructure. Agentcy performs comprehensive DNS lookups to show you A, AAAA, MX, TXT, NS, CNAME, and SOA records — plus email authentication analysis for SPF, DKIM, and DMARC.
Ask about your DNS configuration, email setup, nameservers, or specific record types. Agentcy resolves the records and presents them in a clear, organized format with email deliverability insights.
This is a zero-config service using public DNS resolution — no API key or domain setup required. Enable it and query any domain.

24-hour cache. DNS records reflect the current propagation state at query time.
DNS results reflect the current state — if you've recently made changes, propagation may still be in progress (up to 48 hours)
Some DNS records may not be visible due to zone transfer restrictions
DKIM records require knowing the selector (e.g. google._domainkey) — common selectors are checked automatically
Results come from public recursive DNS, which may differ from what authoritative nameservers show during propagation
