IP Lookup for Security Audits — Analyze Suspicious IPs
Quick Answer: Enter a suspicious IP to check its reputation: ISP/hosting provider, ASN, country of origin, and whether it belongs to a known VPN, proxy, or hosting provider. Useful for investigating brute force attempts, suspicious login locations, and DDoS sources.
IP geolocation is approximate and based on your ISP. VPN or proxy users will see the exit node location. The IP lookup uses ipinfo.io and ipify.org APIs.
FAQ
How do I check if an IP is a VPN or proxy?
Check the ISP name -- hosting companies and VPN providers are identifiable. Also check abuse databases like AbuseIPDB and Project Honeypot for reported activity.
What should I do with a suspicious IP?
Check the ISP (datacenter vs residential), look up abuse history, correlate with your access logs, and consider blocking or rate-limiting. Report to your hosting provider if it is an attack.
