This library provides simple conversion between net.IP and integer (net.IP <--> int). As new feature, library now contains extension of net.ParseIP which returns also byte length of IP address on input.

I hope it will serve you well.

package main
import (
 "fmt"
 "net"
 "github.com/praserx/ipconv"
)
func main() {
 if ip, version, err := ipconv.ParseIP("192.168.1.1"); err != nil && version == 4 {
 fmt.Println(ipconv.IPv4ToInt(ip))
 }
}
