DNS Lookup Tool
Our DNS Lookup Tool allows you to query DNS records for any domain name. Check A, AAAA, MX, TXT, NS, and other record types to troubleshoot DNS issues or verify DNS configurations.
What is DNS?
DNS (Domain Name System) acts as the phonebook of the internet. It translates human-readable domain names (like example.com) into machine-readable IP addresses (like 93.184.216.34) that computers use to identify each other on the network.
Why Use DNS Lookup?
- Troubleshoot email delivery issues by checking MX records
- Verify domain ownership with TXT records
- Identify which name servers are authoritative for a domain
- Check if DNS changes have propagated correctly
- Diagnose website connection problems related to DNS
How DNS Works
When you enter a domain name in your browser, your computer follows these steps:
- Your computer checks its local DNS cache for the domain
- If not found, it queries your ISP's DNS resolver
- The resolver checks with root nameservers
- Root servers direct to the appropriate TLD nameservers (.com, .org, etc.)
- TLD nameservers provide the authoritative nameservers for the domain
- The authoritative nameservers return the IP address for the domain
- Your browser connects to the website using the IP address
