Scope and acceptance
These terms apply when you access or use CIDR Workbench. By using the site, you agree to these terms. If you do not agree, please do not use it.
Informational tool
CIDR Workbench is a free informational IPv4 and IPv6 planning tool. It does not provide professional or technical advice. Outputs must be independently verified before you make production changes, and you remain responsible for your decisions, configurations, and changes.
Limitations and responsibility
The tool does not discover network topology or account for cloud-specific address reservations. Outputs may contain errors, and access may be interrupted. We are not responsible for loss caused by reliance on unverified output, misuse of the tool, or events outside our reasonable control. Nothing in these terms excludes or limits responsibility that cannot legally be excluded or limited.
Acceptable use
Use the site only for lawful purposes. Do not disrupt the site, interfere with other users, attempt unauthorized access, or use it to conduct a security attack.
Third-party links
Links to third-party sites are provided for convenience. A link does not mean that CIDR Workbench endorses or controls the third party or its content.
Privacy
Please read the privacy notice for information about how the site handles data.
Changes to these terms
These terms may be updated from time to time. Changes apply to future use of the site after the updated terms are published here.
