How it works
This tool cross-references an IP against threat-intelligence feeds and WHOIS/ASN data to show its owning network, hosting provider, approximate location, and whether it's associated with reported malicious activity like spam, scanning, or malware distribution.
It's useful for checking a suspicious visitor in your server logs, verifying a sender before trusting an email, or vetting an IP before whitelisting it on your firewall.
Frequently asked questions
Can a shared IP have bad reputation because of someone else's abuse?
Yes — on shared hosting, spam or abuse from a different customer using the same server's IP can drag down the reputation score for every site on that address.
What should I do if my own IP shows a poor reputation?
Check for compromised scripts or outbound spam first, then contact your host or ISP — reputation blacklists usually have a delisting request process once the underlying issue is fixed.
