AbuseIPDB

As anyone who has maintained a website or server knows, the entire Internet is being continually scanned and subjected to malicious attacks attempts like those listed above, which are being carried out en-masse by hackers, spammers, and other bad actors from around the world. These actors use automated software to scan and attack millions of targets twenty-four hours a day - often originating from IP addresses associated with shady hosting companies, botnets, hacked servers, or other machines otherwise controlled by hackers.

While these wide-ranging attacks help hackers raise their chances of finding a vulnerable target to exploit, they also provide the opportunity for webmasters and systems administrators to share their system logs and proactively detect and mitigate attacks coming from IP addresses that are known to be associated with malicious activity.

That's our mission at AbuseIPDB - to provide an easy way for sysadmins to both report malicious IP addresses, and gain access to a crowdsourced list of bad IPs before they've even had the chance to attack your infrastructure.
