Features

Detect Domain Hijacking in the First 10 Minutes

Most domain takeovers leave a visible registration-data signal first: a nameserver swap, a registrant rewrite, or a registrar transfer flagged in the WHOIS status. Domain Monitoring watches all three fields across WHOIS and RDAP and alerts you within 10 minutes, so you can contact your registrar before traffic redirects.

FAQs

FAQs about tracking domain's WHOIS changes over time and timely alerts.

What is domain Monitoring?

Domain monitoring is a service that continuously tracks the WHOIS record of a domain and alerts you when any field changes, including registrant, registrar, nameservers, status codes, or expiry date. WhoisFreaks Domain Monitoring polls as often as every 10 minutes across 1528+ TLDs and delivers alerts by email and Telegram. It catches domain hijacking, unauthorized transfers, and unintentional expirations early enough for the owner to reverse the change.

How to monitor a domain name?

Monitoring a domain name means continuously tracking its WHOIS record for changes to registrant details, nameservers, domain status codes, registrar, and expiry date. You can do this manually by running periodic WHOIS lookups, but that leaves gaps. An automated domain monitoring service checks your domains on a schedule you define (as frequently as every 10 minutes) and sends you an alert the moment any field in the WHOIS record changes, without any manual effort on your part.

To set up domain monitoring with WhoisFreaks, follow these steps:

  1. Access the billing dashboard by sign-in. select monitoring tools > domain monitoring tab for monitoring.
  2. Enter the domain name you wish to monitor into the provided field. This ensures that any changes to this domain's registration details will be tracked.
  3. Customize the monitor settings according to your preferences. You may have the option to exclude certain fields from monitoring if they are not relevant to you.
  4. Ensure that you have configured email alerts within your monitoring settings. This will ensure that you receive notifications promptly whenever changes are detected.
  5. Once the monitoring is set up, you'll receive email alerts whenever changes occur to the domain's registration details. Review the alerts as they come in and take necessary actions based on the detected changes.

By following these steps, you can effectively monitor your domain name and stay informed about any modifications to its registration information.

What types of changes to a domain's WHOIS record can be monitored?

The domain monitoring service is equipped to track every modification or update within the WHOIS record, spanning registrant contact details, administrative and technical contact details, domain status updates, name server changes, and even occurrences of deletion and re-registration unless explicitly excluded by the user. Collectively, these changes can be early indicators of domain hijacking, unauthorized transfers, or registrar fraud.

How are alerts delivered and how frequently?

Alerts are delivered via email and Telegram. Monitoring frequency is configurable from every 10 minutes to every 24 hours. You choose the interval based on your needs. For high-value domains or security-critical assets, 10-minute checks give near real-time detection of any WHOIS change.

Can I monitor multiple domains simultaneously?

Yes, our domain monitoring service allows you to simultaneously monitor multiple domains, providing you with comprehensive oversight and alerts for each domain.

Which TLDs does Domain Monitoring support?

Domain Monitoring supports 1528+ TLDs, including all major gTLDs (.com, .net, .org, .io, .ai, .dev), country-code TLDs (.uk, .de, .in, .cn, .br, and more), and second-level domains (e.g. .co.uk, .com.au, .com.br). See the full list on the Supported TLDs Page.

How fast are alerts delivered?

Domain Monitoring detects a WHOIS or RDAP change at the next polling interval and dispatches the alert within 60 seconds. With every-10-minute polling enabled, the worst-case lag between a registration-data update and an alert in your inbox or Telegram is approximately 11 minutes.

What is domain hijacking and how does domain monitoring help prevent it?

Domain hijacking occurs when an attacker gains unauthorized control of a domain by modifying its WHOIS record, transferring it to a new registrar, or changing its nameservers without the owner's knowledge. Domain monitoring detects these changes the moment they happen and sends you an alert before the hijacker can fully take over, giving you time to contact your registrar and reverse the change.

How do I get notified when a domain I don't own becomes available?

You can add any domain to your monitor list, including domains you don't own. When the domain's status changes to expired, deleted, or available for registration, you'll receive an instant alert. This is useful for acquiring dropped domains, tracking competitor assets, or registering a domain the moment it becomes available.

Does WhoisFreaks Domain Monitoring use WHOIS or RDAP?

Both. ICANN began transitioning gTLD registration data from WHOIS to RDAP on 28 January 2025. WhoisFreaks queries both protocols and returns normalized fields, so the monitor continues to work whether a registry is on WHOIS, RDAP, or in transition. You receive the same alert format regardless of the source protocol.
Catching a hijack in the first 10 minutes is what reverses it

WhoisFreaks Domain Monitoring polls every WHOIS field as often as every 10 minutes and alerts you the moment a value changes, leaving time to contact your registrar and roll back the change.
