Frequently Asked Questions
Everything you need to know about IP address analysis
What is an IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network. It serves as the device's identifier, enabling data to be routed correctly. There are two versions: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:db8::1). Learn more →
What does this IP lookup tool do?
Can this tool detect VPN usage?
Yes. IPSnapshot uses multiple detection methods to identify whether an IP address is associated with a VPN service, proxy server, Tor exit node, or relay network. The results include individual detection flags and an overall risk score. Try the VPN detector →
Is this IP checker free?
Yes, IPSnapshot is completely free to use with no registration required. You can analyze any public IP address for geolocation, security threats, and network information at no cost.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (e.g., 192.168.1.1) with about 4.3 billion possible addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) with a virtually unlimited address space. Both are fully supported by IPSnapshot. Read the full guide →
How accurate is IP geolocation?
IP geolocation is typically accurate to the country level (95-99%) and city level (50-80%). Accuracy can vary based on the ISP, whether a VPN is in use, and the specific database. Mobile and satellite connections tend to be less accurate. Learn more about geolocation →
