func resolveHostIp() (string) {

    netInterfaceAddresses, err := net.InterfaceAddrs()

    if err != nil { return "" }

    for _, netInterfaceAddress := range netInterfaceAddresses {

        networkIp, ok := netInterfaceAddress.(*net.IPNet)

        if ok && !networkIp.IP.IsLoopback() && networkIp.IP.To4() != nil {

            ip := networkIp.IP.String()

            fmt.Println("Resolved Host IP: " + ip)

            return ip
        }
    }
    return ""
}
