IP Lookup
Geolocation, ASN, ISP and org for any IPv4 or IPv6 address.
About the IP Lookup Tool
The IP Lookup tool returns comprehensive information about any IPv4 or IPv6 address — geographic location (country, region, city), ASN (Autonomous System Number), ISP or hosting provider, organization name, and network range. It combines several public data sources into a single view so you don't have to bounce between whois-ip, ipinfo.io and geolocation services.
Security analysts, network engineers, fraud teams, marketers and developers all need to know 'what is this IP?' in different contexts. A SOC analyst tracing a suspicious login wants ISP and country. A performance engineer debugging a slow endpoint wants the ASN and network range. A developer allowlisting a partner's outbound traffic wants both the current IP and the CIDR block it belongs to. This tool answers all three in one lookup.
Geolocation accuracy varies. Country-level data is typically 95%+ accurate; city-level is 60-80% depending on the ISP. Mobile carriers and VPN exit nodes can appear thousands of miles from the actual user. For applications where accuracy matters (fraud, compliance, tax) always corroborate with additional signals rather than trusting geolocation alone.
