This IP Abuse Checker is probably the most comprehensive tool to find out who owns an IP address, domain or website, including abuse score, spam reputation, certificate info and ping response. It is useful for locating the origin of unwanted emails or the source of spam, virus and attacks.

If you enter an IP Address, we are querying the RIPE database for all relevant owner information, check if it has a reverse DNS record and show the geographical location of the IP address.

If you enter a Domain Name, we make a WHOIS query and show the public owner and registration information from the authoritative domain registry. We will show all DNS entries, and if there is an SSL/TLS web server running, we also check if the TLS certificate is valid. By the way, website URLs can be pasted directly into the search field, no need to manually extract the domain. Internationalized Domain Names may be used.

In both cases, we finally perform an abuse check and show if the IP address was reported for fraudulent or malicious activity and if it is listed on major spam block lists. If malicious activity was detected, a calculated Abuse Score is shown together with technical details of the most recent abuse reports.

We also check if IP addresses are responding to ICMP Ping requests and show the response time measured from a large datacenter in Germany. Being fully IPv6 ready, you can use it for quick IPV6 accessibility checks.

This online tool is ad-free. If you like it, please help spread the word about it!
