Frequently asked questions

Why does DNS lookup take time?

The tool performs a live DNS query. Network latency and the domain's authoritative server response time affect speed. A timeout limit of 20 seconds applies.

What is an MX record?

Mail Exchange records specify which servers handle email for the domain, with priority values (lower = preferred).

Can I query any domain?

Yes, any publicly resolvable domain. Private/internal DNS zones are not accessible from this server.
