Look up MX, NS, TXT, CNAME, or A records for any domain. Check whether a domain can receive mail, confirm SPF/DKIM/DMARC TXT records, see name server delegation, or find where a domain points.
An MX (Mail Exchange) record tells the internet which servers are responsible for accepting email on behalf of a domain, in priority order. No MX records usually means the domain can't receive mail.
A records point a domain to an IPv4 address. NS records declare which name servers control the domain. TXT records hold arbitrary text — commonly SPF, DKIM, and domain-verification values. CNAME records alias one hostname to another. MX records declare where email should be delivered.
SPF, DKIM, and domain-ownership verification (Google Search Console, etc.) are all published as TXT records. Checking here confirms exactly what's live right now, without needing access to the domain's DNS panel.
No. Every lookup queries Cloudflare's public DNS resolver directly from your browser. Only the domain you're checking is sent — never stored, never logged by this site.
