Free IP Address Lookup
Geolocation, ASN, abuse reputation, open ports and historical hostname assignments — across 47 threat-intel feeds.
What is free ip address lookup
An IP address tells you who, where, and how. Skopio aggregates ARIN/RIPE/APNIC WHOIS, MaxMind/IPinfo geolocation, AbuseIPDB and 47 threat-intel feeds, Shodan-style port indexes, and historical reverse-DNS. The first IP lookup every day is free, no registration. Built for ops engineers, threat hunters, and curious individuals.
Why it matters
Every login alert, suspicious connection, abusive scraper, and DDoS source has an IP. Knowing whether it is a residential proxy, a Tor exit, a known scanner, or a compromised cloud instance changes how you respond. Free IP lookup pulls all signals into one report.
Who uses it and why
Real scenarios from different teams

WHOIS for an IP from an internal alert. Allocation, contact, country?
Need to verify VPN works, IP geo matches expected country.
