What DNS records are
DNS records define how a domain works: A and AAAA point to the site's IP addresses, MX to mail servers, NS to DNS servers, TXT holds SPF and verifications, CNAME holds aliases. They're handy for diagnosing domain issues.
Checking MX, CNAME and TXT records
Checking MX records shows a domain's mail servers and their priorities — useful for mail setup and delivery diagnostics. Checking a CNAME record reveals which domain an alias (e.g. www or a subdomain) points to. Checking a TXT record lists SPF, DKIM, DMARC and domain-verification codes. All three are shown here at once, together with A, AAAA and NS.
