    DNS Lookup FAQ

    Common questions about DNS records and how this tool works.

    This tool queries the global DNS resolver network to fetch live records directly from authoritative name servers. Lookups are encrypted for privacy and require no API key or account. Results reflect current DNS state worldwide.

    DNS records have a TTL (Time to Live) value that controls how long resolvers cache them. After making a change, you must wait at least as long as the record's previous TTL before all resolvers reflect the new value. Use this tool to confirm when propagation is complete.

    MX (Mail Exchanger) records specify which mail servers receive email for your domain. The priority number before the hostname indicates preference — lower numbers are tried first. If your domain has no MX records, email delivery to that domain will fail.

    TXT record values are returned as quoted strings in DNS responses. Common uses include SPF (email sender policy), DMARC (email authentication), DKIM public keys, and domain verification codes for services like Google Search Console.

    SOA (Start of Authority) is an administrative record for a DNS zone. It identifies the primary name server, the responsible party's email address, a serial number for zone versioning, and refresh/retry/expire timing values used by secondary servers.

    Yes. You can enter any fully-qualified hostname — www.example.com, mail.example.com, api.example.com — and the tool will query DNS for that exact name.
