Frequently asked questions
What domain changes does this monitor track?
It watches the WHOIS registrant, registrar, nameservers, DNS records, and expiration date for the domain. The AI alerts you when any of these change, because they can signal a transfer, a hijack attempt, or an approaching lapse. It ignores ads, cookie banners, and navigation so you only see meaningful updates.
How quickly will I be alerted to a WHOIS or DNS change?
Pick instant alerts to be notified as soon as a change is detected, which helps you respond fast to a suspicious registrar switch or nameserver change. If you would rather review periodically, a daily or weekly digest gathers all detected changes into one summary so nothing slips past you between checks.
Do I need to own the domain to monitor it?
No. As long as the WHOIS, DNS, or expiration details appear on a public lookup page you can open in a browser, you can paste that URL and start watching. This makes it easy to keep an eye on your own domains as well as brand-adjacent names you do not control.
