Look Up DNS Records

Utilook server · external DNS lookup On submission, the domain and record type are sent to Utilook and queried through Cloudflare DNS. This feature does not save inputs or results to a database. Do not enter confidential hostnames. Privacy Policy

Enter a public domain name, not a URL. Each request looks up one selected record type.

What Is a DNS Record?

DNS records connect domain names to IP addresses, mail servers, and other internet service information. A and AAAA store addresses, MX identifies mail servers, NS identifies name servers, and TXT can hold policy and verification data.

Choosing the record to inspect

Use A or AAAA for web-server addresses, MX for mail routing, NS for authoritative name servers, CNAME for aliases, and TXT for verification or email policies. CAA can restrict which certificate authorities may issue certificates for the domain.

Interpreting TTL and propagation

TTL is a cache lifetime, not a promise that every resolver updates at the same moment. After a DNS change, old answers can remain visible until intermediate caches expire; an empty result may also simply mean that the selected record type is not configured.

Where the query goes

Your browser sends the domain and selected record type to Utilook's server, which queries Cloudflare's DNS-over-HTTPS resolver. That external resolver also receives the domain and type. This feature does not save the input or DNS answers in its database; a successful lookup increments only the tool-use count.
