Supported Record Types

DNS (Domain Name System) is the phonebook of the internet. Our tool lets you query the most common record types to ensure your domain is routing correctly.

A / AAAA RecordsCheck the IPv4 or IPv6 address associated with the domain.
CNAME RecordsVerify canonical names mapping domain aliases.
MX RecordsCrucial for troubleshooting business email delivery.
TXT RecordsValidate SPF, DKIM, and site ownership records.

How Check DNS Records

  1. Enter Domain: Type the target website URL or domain name (e.g., example.com).
  2. Select Type: Choose the specific DNS record (A, MX, TXT) you want to query.
  3. Run Lookup: Click the lookup button to query public servers.
  4. Analyze: Review the raw JSON output showing TTL, target values, and resolution arrays.

Frequently Asked Questions

What does "DNS Propagation" mean?
↓
When you change your domain's DNS records, it takes time for those changes to update across all servers worldwide. This period is called propagation and can take anywhere from a few minutes to 48 hours depending on the TTL.
What is a TTL?
↓
TTL stands for Time To Live. It tells servers how long to cache a DNS record before requesting a fresh update. A lower TTL means changes propagate faster.
Why are my emails not being delivered?
↓
Email delivery issues are usually tied to incorrect or missing MX and TXT records. Use this tool to verify your MX records point to your mail server and your TXT records contain valid SPF/DMARC policies.
