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. If you enter a Domain Name, we make a WHOIS query and show the public owner and registration information from the authoritative domain registry. 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. It is useful for locating the origin of unwanted emails or the source of spam, virus and attacks. 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.
