ADVANCED DNS LOOKUP FEATURES

Complete DNS lookup, parsed & readable.

Raw DNS outputs can be hard to digest. We query, parse, and structure every record type into a clean format tailored for developers, sysadmins, and domain administrators.

Check 8 DNS record types at once

Query A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA records in a single lookup and view results in a clean, filterable interface.

SPF, DKIM & DMARC email health check

Automatically analyze SPF, DMARC, DKIM, and CAA security records to score domain email deliverability and spoofing protection.

Instant DNS record filtering

Filter between DNS record types with one click. Isolate MX lookup results or review full DNS propagation in a two-column grid.

FAQ

DNS records & lookup, explained.

An A record points a domain directly to an IPv4 address. A CNAME (Canonical Name) record maps a subdomain to another domain name. You cannot use a CNAME at the root apex domain (example.com), which is why A records are used for root domains and CNAMEs for subdomains like [www.example.com](https://www.example.com).
MX (Mail Exchange) records specify the mail servers responsible for accepting incoming emails on behalf of your domain. Priority numbers control delivery order — lower numbers indicate higher priority, allowing backup servers to handle traffic if the primary mail server goes down.
These TXT records form the core email authentication stack. SPF defines authorized senders, DKIM adds a cryptographic signature to outgoing mail, and DMARC instructs receiving servers how to handle unverified emails (none, quarantine, or reject) to prevent domain spoofing.
DNS propagation speed depends on each record's TTL (Time-To-Live) value, which tells DNS resolvers how long to cache data. Until TTL expires, servers worldwide will serve cached records. A low TTL (300s) updates in ~5 minutes, while high TTLs (86400s) can take up to 24 hours.
CAA (Certification Authority Authorization) records specify which Certificate Authorities (CAs) are authorized to issue SSL/TLS certificates for a domain. Restricting certificate issuance to trusted CAs (like Let's Encrypt or DigiCert) prevents unauthorized or rogue SSL certificate creation.
An SOA (Start of Authority) record contains core administrative information about a DNS zone. It specifies the primary nameserver, domain administrator contact email, zone serial number, and refresh intervals used for DNS zone transfers between nameservers.
