Fork of haoel/ipsearch with IPv6 support.
A simple library to search for IP(v4 & v6) addresses for one IP database: IP CIDR List.
The library use the cidr list of herrbischoff/country-ip-blocks.
package main
import (
"fmt"
"github.com/guuzaa/ipsearch"
)
// ipv4 version
func main() {
search, err := ipsearch.NewIPv4SearchWithFile("./data/ipv4/cn.cidr")
if err != nil {
panic(err)
}
ipStr := "114.114.114.114"
ip := search.Search(ipStr)
if ip != nil {
fmt.Printf("IP [%s] is in China\n", ipStr)
} else {
fmt.Printf("IP [%s] is not China\n", ipStr)
}
}
// ipv6 version
func main() {
search, err := ipsearch.NewIPv6SearchWithFile("./data/ipv6/cn.cidr")
if err != nil {
panic(err)
}
ipStr := "2001:da8::2"
ip := search.Search(ipStr)
if ip != nil {
fmt.Printf("IP [%s] is in China\n", ipStr)
} else {
fmt.Printf("IP [%s] is not in China\n", ipStr)
}
}package main
import (
"fmt"
"github.com/guuzaa/ipsearch"
)
// ipv4 version
func main() {
search, err := ipsearch.NewIPv4SearchWithCountry("cn")
if err != nil {
panic(err)
}
ipStr := "114.114.114.114"
ip := search.Search(ipStr)
if ip != nil {
fmt.Printf("IP [%s] is in China\n", ipStr)
} else {
fmt.Printf("IP [%s] is not China\n", ipStr)
}
}
// ipv6 version
func main() {
search, err := ipsearch.NewIPv6SearchWithCountry("cn")
if err != nil {
panic(err)
}
ipStr := "2001:da8::2"
ip := search.Search(ipStr)
if ip != nil {
fmt.Printf("IP [%s] is in China\n", ipStr)
} else {
fmt.Printf("IP [%s] is not in China\n", ipStr)
}
}As haoel did, the ipsearch package is using the Hash Table and Binary Search algorithm. Apart from that, we use the net/ip package to parse IP address.
