About DNS Lookup (A, AAAA, MX, TXT, CNAME, NS, SOA)
The DNS Lookup tool retrieves DNS records for a domain, including A, AAAA, MX, TXT, CNAME, NS, and SOA. Enter a domain name, choose the record type you want, and the matching records are listed in the results.
The domain you enter is sent to Cloudflare's DNS-over-HTTPS endpoint, which resolves the query and returns the records the tool displays. This is useful for confirming that a site points to the right server, checking mail routing through MX records, or verifying TXT entries such as SPF and domain ownership tokens.
Frequently asked questions
- What is DNS-over-HTTPS?
- It is a method of sending DNS queries over an encrypted HTTPS connection, which this tool uses through Cloudflare's resolver.
- Why do MX records matter?
- MX records tell other mail servers which hosts accept email for a domain, so they are key when troubleshooting delivery.
- Why might a record I just changed not appear?
- DNS records are cached for a period set by their TTL, so a recent change can take time to be visible everywhere.
