ABOUT THIS SERVICE
About nslookup.online
A focused reference tool for reading public DNS responses.
A direct answer, with its limits
nslookup.online is a multilingual DNS reference and query interface. The tools ask a selected public recursive resolver and explain the returned records. They do not edit DNS, inspect your local network, send email or certify a domain as safe.
Where answers come from
Queries are sent from your browser to Google Public DNS or Cloudflare 1.1.1.1 over HTTPS. The selected source, query name, record type and completion time accompany the result. No additional server or account is needed for this version.
DMARC policy discovery targets RFC 9989. SPF inspection uses the static configuration scope described in the tool, based on RFC 7208. Neither tool authenticates a message.
Before public launch
This is a local development preview. Operator identity, a public support channel, production hosting details and the final legal review have not been supplied or approved. These are launch requirements, not details that the development version invents.
