Checking DNS Records for Domains and Infrastructure

DNS records control how a domain points to websites, mail servers, verification systems, security policies, and infrastructure services. A small DNS mistake can affect website availability, email delivery, domain verification, or application routing.

This DNS Records Checker helps developers, site owners, SEO teams, and DevOps users quickly inspect common DNS records such as A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA records.

How to Use the DNS Records Checker

  1. Enter a domain name such as example.com.
  2. Select all records or choose a specific DNS record type.
  3. Click Check DNS Records.
  4. Review record values, TTLs, and configuration details.
  5. Copy results if you need to share them with a developer or team.

DNS Records Commonly Checked

  • A records point a domain to IPv4 addresses.
  • AAAA records point a domain to IPv6 addresses.
  • CNAME records point one hostname to another hostname.
