What is a DNS lookup?

A DNS lookup translates a human-readable domain name (e.g. example.com) into its IP address and associated records. DNS records include A (IPv4 address), AAAA (IPv6), MX (mail servers), NS (name servers), CNAME (alias), TXT (arbitrary text) and SOA (zone authority).

What DNS record types does GoChronos support?

The tool checks A, AAAA, CNAME, MX, NS, TXT, SOA and PTR records. Select the record type from the dropdown to query a specific record type.

What is an MX record?

An MX (Mail Exchange) record specifies which mail servers accept email for a domain. Multiple MX records can coexist with different priorities; lower priority numbers indicate preferred servers.

What is a TXT record used for?

TXT records contain arbitrary text. Common uses include domain ownership verification (Google Search Console, GitHub, etc.), SPF (Sender Policy Framework) for email authentication, DKIM public keys and DMARC policies.

Is the DNS lookup tool free?

Yes. Free on GoChronos, no account required.
