What DNS record types can I look up?

The tool queries all major record types: A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail servers), CNAME (aliases), TXT (text data including SPF/DKIM), NS (name servers), and SOA (authority information).

What is DNS propagation and why does it take time?

DNS changes can take minutes to hours to propagate across the internet because DNS servers cache records for their TTL duration. The tool queries DNS servers directly, so you see the current state including whether changes have propagated.

How do I check if my SPF record is correct?

Look up the TXT records for your domain. The SPF record is the TXT record starting with v=spf1. Check that it includes all authorized mail servers and ends with an appropriate policy (e.g., ~all or -all).

Why are my MX records important?

MX records direct email to the correct mail servers. Incorrect MX records cause emails to bounce or be delivered to the wrong server. Verify that MX records point to your actual email provider servers.

Can I use this tool to check any domain?

Yes. The tool works for any public domain name. You do not need to own or administer the domain to query its DNS records. This is useful for verifying competitor configurations or checking third-party services.
