Frequently asked questions

What is a DNS lookup?

DNS lookup is the process of converting a domain name (like example.com) into the DNS records that describe where it points, who hosts it, and how email is delivered.

What DNS record types can I check?

This tool checks A (IPv4), AAAA (IPv6), MX (mail), TXT (SPF/DKIM), NS (nameservers), CNAME (aliases), SOA (start of authority), and CAA (certificate authority) records.

How fast is the lookup?

Sub-100ms. We use Cloudflare DNS (1.1.1.1) via DNS-over-HTTPS, which is one of the fastest public resolvers globally.

Is this the same as nslookup?

Yes — it performs the same function as the nslookup and dig commands, but runs in your browser without requiring any software installation.
