Terms of Use
Last updated: 11 November 2026
These terms govern your use of Nexus Domain Tools ("the service"), a free set of network diagnostics operated by Segbytes. By using the service you accept them.
What the service is
A free, best-effort toolbox for looking up public DNS records, WHOIS registration data, email security posture, TLS certificates, and related diagnostics. It requires no account and is supported by disclosed partner offers and our paid products.
No warranty, informational only
- The service is provided "as is", without warranty of any kind, express or implied, including accuracy, availability, or fitness for a particular purpose.
- Results come from third-party sources (DNS resolvers, WHOIS registries, certificate authorities, blacklist operators) and are informational only — not legal, security, or compliance advice. Verify critical findings through official channels.
- There is no SLA. Endpoints, limits, or the service itself may change or be discontinued.
Fair use
- Rate limits apply per IP and per endpoint. Automated or bulk use must respect them; the service may throttle or block abusive traffic.
- Do not attempt to bypass rate limits, bot protection, or access restrictions, and do not use the service for scanning, harvesting, or attacking third parties.
- You are responsible for the legality of the targets you query and what you do with the results.
- Programmatic use should set a descriptive User-Agent and stay within limits; see the
ai.txtandrobots.txtnotices for crawler policy.
Disclosed partner offers
When a check fails or something is expiring, the service may surface clearly-labelled offers from partners (registrars, email vendors). We may earn a commission from those. Offers never affect check results, and are shown only at the moment of the relevant failure.
Limitation of liability
To the maximum extent permitted by law, Segbytes is not liable for any indirect, incidental, or consequential damages, or for any loss arising from use of, or inability to use, the service, or from reliance on its results.
Governing law
These terms are governed by the laws of South Africa. Questions or reports: GitHub issues or segbytes.co.za. Changes to these terms are posted on this page with an updated date.
