A (Address) — Maps a domain name to an IPv4 address. Every website relies on A records to point visitors to the correct server.

AAAA (IPv6) — Maps a domain name to an IPv6 address. Used alongside or instead of A records for networks that support IPv6.

MX (Mail Exchange) — Specifies the mail servers responsible for receiving email on behalf of a domain. Priority values determine the order servers are tried.

CNAME (Canonical Name) — Aliases one domain to another. Common for www subdomains and CDN integrations.

NS (Name Server) — Delegates a domain to authoritative name servers. Changing NS records is how you point a domain to a different DNS provider.

TXT (Text) — Stores arbitrary text data. Used for SPF, DKIM, DMARC email authentication, domain verification, and other security policies.

SOA (Start of Authority) — Contains administrative metadata about the zone: primary name server, admin contact, serial number, and refresh/retry/expiry intervals.

SRV (Service) — Defines the location (hostname and port) of specific services like SIP or XMPP. Weight and priority control load balancing.

Use this tool to verify your DNS configuration, troubleshoot email delivery, check propagation of recent changes, or audit your domain's security posture.
