Web Site Terms and Conditions of Use

1. Your agreement with ipwhois

By accessing or using ipwhois.io (“we”, “us”, or “our”), you agree to these Terms of Use and any applicable laws and regulations. If you do not agree with these Terms, please do not use our website or services. Materials here are protected by copyright and trademark laws.

2. License Grant

  1. We grant you a limited, non-exclusive, non-transferable right to access and use our website, API, documentation, and related materials for your personal or internal business purposes. You agree not to:
    1. copy, modify, resell, sublicense, or redistribute our materials or services without our prior written permission;
    2. reverse-engineer, decompile, disassemble, or attempt to access the source code of our software, except where permitted by applicable law;
    3. transfer, mirror, frame, or make our materials or services available on other servers or platforms without our prior written permission.
  2. We may suspend or restrict access if we reasonably believe these Terms are being violated. Where practical, we will try to notify you and work with you to resolve the issue.

3. User Obligations

  1. Register using a valid corporate or personal email.
  2. You agree not to disrupt, interfere with, overload, or otherwise harm the operation, security, or performance of ipwhois.io.
  3. Your account and API access are intended for your own use or your organization’s internal business use, and you should not share credentials with unauthorized third parties.
  4. You are responsible for keeping your API keys, passwords, and account credentials secure.
  5. We may temporarily limit, suspend, or deactivate access in cases of abusive, unlawful, or excessive usage that may harm the service, other users, or our infrastructure. Where practical, we will attempt to contact you first.
  6. You agree to use the API only for lawful purposes and not to use it for spam, fraud, malicious activity, unauthorized scraping, abuse, or any activity that violates applicable law or third-party rights.

4. Disclaimer

Our services and data are provided on an “as is” and “as available” basis. While we work to provide accurate and reliable data, we cannot guarantee that the data will always be complete, accurate, uninterrupted, error-free, or suitable for every specific use case. To the maximum extent permitted by law, we are not liable for indirect, incidental, consequential, special, or punitive damages arising from the use of our services.

5. Data Sources

We compile and process data from multiple sources, including public registries, geofeeds, latency tracking, and trusted third-party data providers. These sources may include RIPE, APNIC, ARIN, AFRINIC, and similar registries.

For some IP ranges we use GeoLite2 data generated by MaxMind, available at www.maxmind.com

6. Payment and return policy

Paid subscriptions may be billed monthly or annually, depending on the plan selected. You may cancel your subscription at any time through your dashboard. After cancellation, your paid service will remain active until the end of the current billing period. Refund requests may be submitted within 7 days of the payment date. Each refund request is reviewed individually and approval is not guaranteed.

7. Rate Limits and Fair Use Policy

Users may be subject to rate limits, which can vary depending on the selected subscription plan.

For plans that include unlimited requests, “unlimited” means there are no fixed request limits per month or per minute, so you can make as many requests as your business needs. At the same time, we apply a Fair Use Policy only to help keep the service stable, reliable, and available for all customers.

Fair Use means using the service in a reasonable way for your own business needs and avoiding usage patterns that could negatively affect the performance, availability, or cost of the service.

We reserve the right to temporarily or permanently limit access to the API in cases of misuse, including but not limited to:

  1. excessive request volumes generating traffic comparable to DDoS activity;
  2. resale, sublicensing, or unauthorized sharing of API keys with third parties;
  3. systematic querying of IP ranges for the purpose of replicating the database;
  4. any other usage patterns that fall outside reasonable and fair consumption of the service.

If we identify unusual or excessive usage, we may contact you to discuss possible solutions, such as optimization, temporary limits, or moving to an enterprise plan with custom terms.

8. Data Privacy and Compliance

  1. We care about privacy and aim to handle personal information responsibly, including in accordance with applicable data protection laws such as GDPR where applicable.
  2. You are responsible for ensuring that your usage of our API complies with any applicable data privacy regulations in your jurisdiction, especially when processing or storing personal information.

9. Service Availability, Maintenance, and SLA

  1. We strive to maintain 100% availability of the ipwhois.io API and related services. Planned maintenance is normally performed without affecting customers, as we use redundant servers to maintain service continuity during maintenance or isolated failures. However, emergency work, security-related actions, or incidents beyond our control may occasionally cause temporary interruptions, restrictions, or degraded performance. Where practical, we will try to minimize disruptions and provide notice of planned maintenance.
  2. The Free plan is provided on an “as is” and “as available” basis and does not include any uptime SLA, service credit, refund, or availability guarantee.
  3. Paid subscription plans may include an uptime SLA depending on the selected subscription plan. The applicable uptime SLA may range from 99.9% up to 100%, as specified in the plan details or in a separate written agreement with us.
  4. If the API is unavailable for more than forty (40) minutes during a calendar month, eligible paying customers may request a service credit equal to the subscription fee for the following month. To request this credit, the customer must contact us and provide reasonable evidence of the outage, including timestamps, request logs, error responses, monitoring reports, or other relevant technical information.
  5. Service credits are not issued automatically. The request must be submitted within thirty (30) days after the end of the month in which the claimed outage occurred. After review, if we confirm that the downtime qualifies under this SLA, we will apply the credit to the customer’s next billing period. This service credit is the customer’s sole and exclusive remedy for availability-related issues.
  6. The SLA does not apply to downtime, interruptions, errors, latency, or degraded performance caused by:
    1. failures, congestion, routing issues, or outages in third-party networks, internet providers, DNS providers, hosting providers, or other infrastructure outside our reasonable control;
    2. issues caused by the customer’s systems, applications, configurations, code, network, firewall, proxy, DNS, or other client-side infrastructure;
    3. planned maintenance, where reasonable notice is provided when practical;
    4. emergency maintenance, security incidents, abuse prevention, or actions required to protect the service, our infrastructure, or other users;
    5. DDoS attacks, denial-of-service events, bot attacks, malicious traffic, or other attacks against our service or infrastructure;
    6. suspension, limitation, or blocking of the customer’s account or API access due to violation of these Terms, the Fair Use Policy, abuse, unlawful activity, non-payment, or other misuse.

10. Modification of Terms

We may modify the terms without prior notice. Continued use of the site indicates agreement with the latest terms. You may reject changes by closing your account. Contact us at [email protected] for any inquiries.
