What is a DNS Lookup?

The Domain Name System (DNS) is often called the "phonebook of the internet." It translates human-readable domain names (like `example.com`) into computer-readable IP addresses.

Our DNS Lookup Tool performs an instant query against public nameservers to retrieve the raw DNS records associated with any domain. This allows webmasters and IT administrators to see exactly where traffic, emails, and subdomains are being routed.

Common Record Types Checked

  • A & AAAA Records: Points a domain to its host server's IPv4 or IPv6 address. Crucial for website hosting.
  • MX Records: Mail Exchange records dictate which servers are responsible for handling emails sent to the domain.
  • TXT Records: Used heavily for domain verification and email security protocols like SPF, DKIM, and DMARC.
  • NS & CNAME: Defines the authoritative Nameservers and Alias configurations.

How to Use the Lookup Tool

  1. Enter the root domain name in the input box (e.g., google.com). Do not include https:// or www.
  2. Click the "Perform DNS Lookup" button.
  3. The tool will instantly query the server and output a formatted list of all publicly available A, MX, NS, TXT, and CNAME records.

Frequently Asked Questions (FAQ)

Why aren't my new DNS records showing up?

If you recently updated your domain settings at your registrar (like GoDaddy or Cloudflare), it can take anywhere from a few minutes to 48 hours for the changes to update globally. This delay is known as DNS Propagation, dictated by the record's TTL (Time To Live).

How do I verify my email is secure?

To ensure your emails aren't marked as spam, you need to check your TXT records. You should look for strings containing `v=spf1` (SPF record) and your DKIM keys. If they are missing here, your email deliverability will suffer.

What does an "Invalid domain format" error mean?

This means you entered a URL instead of a domain name. Please strip away the protocol and paths. Use example.com instead of https://www.example.com/page.
