How to use the DNS Lookup

Enter a domain name.
Click Look up.
Review the records and the email-authentication notes.

Records are queried through our server’s DNS resolver, so recently changed records may still show cached values until their TTL expires. The tool also checks for SPF and DMARC records, which help protect a domain against email spoofing.

Frequently asked questions

Why don’t I see my new record?

DNS changes take time to propagate; resolvers keep old answers until the TTL (time to live) expires.
