Check DNS records for any domain — MX, A, NS, TXT, and CNAME. Instant results from global DNS resolvers.
An MX (Mail Exchange) record is a DNS record that specifies which mail server receives email on behalf of a domain. MX records include a priority value — lower numbers have higher priority.
Enter the domain name above and click Lookup. The tool queries DNS servers and displays all MX, A, NS, TXT, and CNAME records for that domain instantly.
MX records tell the internet where to deliver email for your domain. Without correct MX records, email sent to your domain will bounce or be undeliverable.
TXT records hold text data including SPF (sender verification), DKIM (email signing), and DMARC (authentication policy) records. These protect your domain from spoofing and improve deliverability.
