Because the usage of IP4 and ip6 is always changing, the query results cannot be guaranteed to be 100% accurate. In addition to providing maxmind's data results, we also provide ip address lookup query results from other data sources, such as: iP2location, etc.
IPv4 is short for Internet Protocol version 4. IPv4 is currently used by most network devices. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly.
An IPv4 address is a 32-bit address that identifies a device on a network. It is made of 4 groups of numbers (octets) with up to 3 numbers each. Each of the four numbers can range from 0 to 255.
Here you have an example of an IPv4 address: 210.126.91.151
IPv6 stands for Internet Protocol version 6, and it is the newer version of the Internet Protocol (IP). IPv6 is the replacement for the aging IPv4. An IPv6 address consists of 8 groups of four hexadecimal digits (0-9 and a-f) separated by colons and looks like this CDCD:910A:2222:5498:8475:1111:3900:2020. If one of the groups only contains zeros, that group can be omitted.
