useforfreeWhat this does
This DNS lookup asks public DNS servers about a domain and shows every common record: where the website and email go, which name servers are in charge, verification and SPF text records, and who may issue its SSL certificates. It also shows which company hosts each address, whether the domain is protected by DNSSEC, and the name behind an IP address. Switch between Cloudflare and Google DNS to check that a change has spread.
How to use it
- Type a domain such as example.com, a full web address, or an IP address.
- Pick the records you need, or leave "All common".
- Press Look up. Copy the page address to share the result.
FAQ
Why don't I see my new DNS record yet?
DNS servers keep answers for the record's TTL (time to live). After a change, wait for the old TTL to pass, then look again. Comparing Cloudflare and Google DNS shows whether the change has reached both.
What do the record types mean?
A and AAAA point a name to an IPv4 or IPv6 address, CNAME makes it an alias, MX lists the mail servers, NS the name servers, TXT holds text such as SPF and site verification, and CAA says which authorities may issue SSL certificates.
What is DNSSEC?
DNSSEC signs a domain's records so resolvers can check they weren't tampered with. Validated means the signatures checked out.
