Due to restrictions imposed by some registrars on their WHOIS servers, there may be instances where WHOIS-based information is unavailable or returns as null. This issue does not seem to be isolated to a single registrar or specific domain type; it can occur unpredictably across various domains. If you encounter a one-time alert, we recommend double-checking the domain’s DNS configuration. In these cases, the WHOIS server may have been temporarily unable to retrieve data during the inspection. However, if you receive frequent alerts, please reach out to our support team. This will allow us to track the issue closely and keep you updated as we work toward a more comprehensive solution. We are actively investigating ways to address this challenge more effectively, and we truly appreciate your patience and understanding.
