How it works
01
Resolve DNS
The domain's records reveal the IP addresses it is served from. Domains that do not resolve stop here.
02
Read RDAP
The registrar abuse email, phone or form comes straight from the domain's registration record.
03
Query abuse sources
Each IP is checked against public abuse-contact sources and a curated map of hosting provider reporting forms.
For an IP address, only the hosting lookup runs. Registrar abuse contacts are what ICANN requires every accredited registrar to publish, so a result here is almost always the right channel for a domain-level complaint. Our guide to reporting domain abuse to a registrar walks through the full submission and escalation process.
When to report domain abuse
Send an abuse report when a domain is used for phishing, impersonation, malware or fraud against your brand. Registrars can suspend the domain; hosting providers can take down the content served from their network. Our guide to reporting hosting abuse covers finding the origin host behind a reverse proxy. Include the evidence you observed, such as screenshots, dates and the offending URL, since abuse desks act on verifiable reports. The provider abuse contacts directory lists the verified channel and requirements for each major provider. If you need detection rather than a one-off lookup, domain monitoring surfaces new lookalike registrations the day they appear.
