Lookup public IP details including ASN, ISP, country, region, city, and timezone using stable free API-backed checks.
Only includes checks that are practical with stable free APIs and lightweight server-side routes.
Lookup ISP, ASN, geo-region, and timezone for a public IP.
IP addresses carry more context than most developers inspect. The IP Lookup Tool surfaces geolocation, ASN, ISP, and organization data for any IPv4 or IPv6 address — useful for access control debugging, security auditing, and geographic content delivery verification.
IP geolocation is accurate to country level with high reliability, city level with moderate reliability, and street level with low reliability. VPN and proxy IPs will map to the datacenter, not the user's physical location.
Pair with DNS Lookup to resolve hostnames to IPs before inspection.
Country-level is highly accurate (99%+). City-level is moderate (50–80%). VPNs and proxies map to datacenter locations, not user locations.
Autonomous System Number — a unique identifier assigned to a network operator (ISP, hosting provider, or large organization) for routing purposes.
Yes. Leave the input blank or enter your current IP address to see what information is publicly associated with your connection.
