Common questions
What is an IP address?
An IP address is the number that identifies a device or network on the internet, like a postal address for data. Your provider assigns your connection one, and websites see it when you visit them.
What is the difference between IPv4 and IPv6?
IPv4 addresses look like 203.0.113.5 and are running out. IPv6 addresses are longer, like 2001:db8::1, and were created to provide far more addresses. Many connections now use both.
What is an ASN?
An autonomous system number (ASN) identifies a large network, such as an internet provider or a hosting company. It tells you who operates the network that address belongs to.
How accurate is the location?
Only roughly. The result usually shows the city or region where the provider routes traffic, which can be many kilometers from the real position. It never shows a street address or a person.
Why does a private address like 192.168.1.1 not work?
Addresses starting with 192.168, 10 or 172.16 to 172.31 are private ones used inside home and office networks. They are not on the public internet, so they have no provider or location to look up.
