Get Started With IP2Location Go Module
Dependencies
This library requires IP2Location BIN database to function. You may download the BIN database at
IP2Location LITE BIN Data (Free): https://lite.ip2location.com
IP2Location Commercial BIN Data (Comprehensive): https://www.ip2location.com
IPv4 BIN vs IPv6 BIN
Use the IPv4 BIN file if you just need to query IPv4 addresses.
Use the IPv6 BIN file if you need to query BOTH IPv4 and IPv6 addresses.
Installation
To install this module type the following:
go get github.com/ip2location/ip2location-go/v9

fmt.Print(err)
return
}
