Terms of Service
By using this tool, you agree to the terms below. This page is a plain-language summary, not a substitute for legal advice.
The service
This tool performs public DNS lookups for domain names you submit -- single, bulk, or on a schedule -- and returns the resolved IPv4/IPv6 addresses. It is provided free of charge, with no account required.
Eligibility
You must be at least 13 years old, or the age of digital consent in your country, to use this service.
Acceptable use
Use this tool only for domains you have a legitimate reason to look up. You agree not to attempt to bypass its security protections -- including probing localhost, private or internal network ranges, or cloud metadata endpoints -- and not to use it for port scanning, subnet scanning, or any form of network reconnaissance beyond public DNS resolution. You agree not to automate requests in a way designed to circumvent rate limits, and not to interfere with the service's availability for other users.
Rate limits
Requests are rate-limited per visitor to keep the service available for everyone. Bulk and scheduled jobs are capped at a maximum number of domains per request. These limits may change without notice.
Advertising
This service may be supported by advertising, including ads served by Google. Ads are served independently of lookup results and never affect what a DNS query returns. See the Privacy Policy for details on advertising cookies.
Intellectual property
The site's design, branding, and underlying code belong to their respective owners. DNS results themselves are public data returned by third-party DNS servers and are not owned by this service.
No warranty
The service is provided “as is” without warranties of any kind. DNS answers reflect what public resolvers return at the time of the request and may change or vary over time. We do not guarantee uninterrupted or error-free operation.
Limitation of liability
To the fullest extent permitted by law, this service and its operators are not liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the service.
Termination
Access may be limited or blocked, without notice, for any use that violates these terms -- including abuse of rate limits or attempts to probe internal infrastructure.
Changes to these terms
These terms may be updated from time to time. The current version is always the one posted on this page. Continued use after a change means you accept the update.
