Why use this tool
DNS (Domain Name System) translates domain names into the IP addresses computers need. This tool queries the public DNS records of any domain so you can verify configurations.
It is the fastest way to confirm whether a domain points where it should, or to debug email (MX), routing (A/AAAA) and verification (TXT) records.

Frequently asked questions
What DNS records should I check?
A/AAAA for the website IP, MX for email, NS for nameservers, and TXT for verification or SPF/DKIM.
How long does DNS propagation take?
Usually minutes to 48 hours depending on TTL values and your provider.
Why is my domain not resolving?
Check nameservers first, then A/AAAA records. Propagation, typos and provider delays are the common causes.
