DNS Lookup
Look up a domain's A, AAAA, MX, TXT, NS and SOA records. The query runs server-side.
Domain
DNS lookup shows which records are currently published for a domain: A/AAAA (IP addresses), MX (mail servers), TXT (including SPF/DKIM-style records), NS (name servers) and SOA (zone data).
Useful when setting up email (checking MX and SPF), migrating a site to new hosting (confirming the A record points to the right IP), adding a subdomain, or just figuring out why DNS isn't behaving as expected.
The query runs server-side, so the result isn't affected by your browser's or local resolver's DNS cache and reflects the zone's current state.
Frequently asked questions
DNS records are cached at several levels (browser, OS, ISP). A server-side query bypasses those caches and shows a fresher state, but a recent change may not have finished propagating to every resolver worldwide yet (the record's TTL determines how long that takes).
It means that record type isn't published for the domain — that's normal. Many domains, for example, have no MX records if they don't handle email.
DNS lookup shows the zone's technical records (where the domain points). WHOIS shows administrative data — who owns the domain, which registrar, and when the registration expires.
