DNS Lookup: Check Any Domain Records

Verify your A, MX, TXT, and CNAME records instantly. Troubleshoot DNS propagation and ensure your website and email are correctly configured.

AI Overview

A DNS Lookup is a query used to find the settings of a domain name. It translates a URL into an IP address and reveals mail server (MX) info. Using a DNS checker is essential for verifying website migrations and confirming that security records like SPF or DKIM are active.

What is the Domain Name System (DNS)?

The Domain Name System (DNS) acts as the phonebook of the internet. It translates human-friendly names like zkbtracking.site into numerical IP addresses that computers use to connect. Without DNS, you would have to remember complex strings of numbers for every website you visit.

Usage Tip: If your website isn't loading after a server change, check the A Record. It must point to your new IP address for the site to go live.

Common DNS Record Types

  • A Record: Maps a domain name to an IPv4 address.
  • MX Record: Directs email to the correct Mail Server.
  • TXT Record: Often used for SPF, DKIM, and DMARC to verify email security.
  • CNAME: Acts as an alias, pointing one domain to another.

Why is DNS Propagation Slow?

When you update a record, it takes time for DNS servers around the world to clear their cache and see the new info. This is called propagation. Depending on the TTL (Time to Live) setting, it can take anywhere from a few minutes to 48 hours to update globally.
