What is DNS Lookup?

A DNS lookup reveals the records that tell the internet how to find your domain. Every time someone visits your website, their browser performs a DNS lookup to translate your domain name into an IP address. Understanding your DNS records is essential for troubleshooting email delivery, website connectivity, and domain configuration.

How to use this tool

  1. Enter your domain name without http:// or www
  2. Click Check to query DNS servers
  3. Review A, AAAA, MX, CNAME, TXT, NS, and SOA records
  4. Use the results to verify your DNS configuration

Frequently asked questions

What are DNS records?
DNS records are entries in a domain name system that map domain names to IP addresses and provide other domain-related information. The most common types are A records (IPv4 addresses), AAAA records (IPv6), MX records (mail servers), CNAME records (aliases), TXT records (verification and security), and NS records (nameservers).
How long does DNS propagation take?
DNS changes typically propagate within 1-48 hours, though most changes take effect within 1-4 hours. The propagation time depends on the TTL (Time To Live) value set on your DNS records and how aggressively DNS resolvers cache records.
Why are my DNS records not showing?
If your DNS records are not appearing, check that your domain is properly registered, your nameservers are correctly configured at your registrar, and the records have been created at your DNS provider. New records may take a few minutes to become available.
