About DNS Records
A / AAAA — Maps a domain to an IPv4 or IPv6 address.
MX — Mail exchange servers for the domain. Priority determines order.
TXT — Arbitrary text: SPF, DMARC, DKIM, site verification tokens.
NS — Nameservers authoritative for this domain.
CNAME — Alias pointing to another hostname (cannot coexist with other records).
SOA — Start of Authority: primary NS, serial, refresh intervals.
CAA — Restricts which CAs may issue SSL certificates for the domain.
PTR — Reverse DNS: maps an IP address back to a hostname.
SPF & DMARC Analysis
When TXT records are found, this tool automatically detects SPF policies, DMARC settings, and DKIM keys. Use the TXT record type to check email deliverability configuration.
