Frequently Asked Questions — IP Address Lookup
How accurate is IP geolocation?
IP geolocation is generally accurate to the city level for most addresses, with accuracy rates around 80-90% for city-level detection. Country-level detection is over 99% accurate. However, VPN users, mobile networks, and corporate proxies may show different locations than the actual user.
What is the difference between IPv4 and IPv6?
IPv4 addresses use 32 bits in dotted decimal format like 192.168.1.1, allowing about 4.3 billion unique addresses. IPv6 uses 128 bits in hexadecimal colon format like 2001:0db8::1, allowing a virtually unlimited number of addresses. Both formats are supported by the lookup tool.
Can I look up any IP address?
You can look up any public IP address. Private IP ranges (10.x.x.x, 172.16-31.x.x, 192.168.x.x) and localhost (127.0.0.1) are not routable on the public internet and will not return geolocation data.
