About IP Address Lookup

IP Address Lookup has been providing free, reliable IP intelligence tools to users worldwide since 2007. What started as a simple IP geolocation tool has grown into a comprehensive platform used by network administrators, security researchers, law enforcement, and everyday users to investigate IP addresses, trace emails, and report malicious activity.

Over the years, our community has filed more than 128,000 abuse reports against malicious IP addresses, helping to document and combat online threats including spam, hacking attempts, phishing, and fraud.

• IP Address Lookup - Geolocation, ISP, hostname, and threat analysis for any IPv4 or IPv6 address
• Email Header Trace - Extract sender IP and trace the origin of any email
• Email Address Lookup - Check if an email address has been reported for abuse
• WHOIS Lookup - Domain and IP registration information
• DNS Blacklist Check - Check IPs against major spam and threat databases including Spamhaus, SORBS, Barracuda, and SpamCop
• Traceroute - Network path analysis to any IP or hostname

We believe in transparency about where our data comes from and how it's used:

• IP Geolocation - Powered by MaxMind GeoIP2 databases, updated regularly for accuracy
• Threat Intelligence - Aggregated from Project Honeypot, StopForumSpam, and community reports
• DNS Blacklists - Real-time queries against Spamhaus SBL, SpamCop, Barracuda, SORBS, and other major RBL providers
• WHOIS Data - Direct queries to regional Internet registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC)
• Malware/Phishing Domains - Sourced from community-maintained blocklists including FireBog and Phishing Army

Geolocation accuracy varies by region: country-level identification is 95-99% accurate, while city-level accuracy ranges from 50-80% depending on the IP range and ISP.

IP Address Lookup provides publicly available information about IP addresses. We do not store personal information about visitors beyond standard server logs.
