# go_tools

---

go_tools is go package for go develop, include ip/ip cidr...

## Features

---

### 1. ip_tools

- go_tools/ip_tools can convert string ip to []byte.

- go_tools/ip_tools can generate random ip / ip cidr.

- go_tools/ip_tools can generate random ip between two ips.

- go_tools/ip_tools can calculate first/last valid ip, boardcase address, network address according to ip cidr.

## Install 

---

```go get -v github.com/zhuliquan/go_tools```

## Example

---

1. useage of ip_tools 

```golang

package main

import (

	"fmt"

	"github.com/zhuliquan/go_tools/ip_tools"

)

func main() {

	if err := ip_tools.CheckValidIp("123.0.0.1"); err == nil {

		fmt.Println("this is valid ip")

	}

	if err := ip_tools.CheckValidIp("123.0.1"); err != nil {

		fmt.Println("this is not valid ip")

	}

	if err := ip_tools.CheckValidIpCidr("126.0.0.8/4"); err != nil {

		fmt.Println("this is valid ip cidr")

	}

	if err := ip_tools.CheckValidIpCidr("126.0.0.9/800"); err != nil {

		fmt.Println("this is not valid ip cidr")

	}

	ip := ip_tools.GetRandomIpV4()

	fmt.Println("get a random ip v4: ", ip)

	ip = ip_tools.GetRandomIpV6()

	fmt.Println("get a random ip v6: ", ip)

	ipCidr := ip_tools.GetRandomIpCidrV4()

	fmt.Printf("Get a random ip cidr v4: %s \n", ipCidr)

	fmt.Printf("accroding to ip cidr %s, network address: %+v\n", ipCidr, ipCidr.GetNetworkAddress())

	fmt.Printf("accroding to ip cidr %s, broadcast address: %+v\n", ipCidr, ipCidr.GetBroadCastAddress())

	fmt.Printf("accroding to ip cidr %s, first valid address: %+v\n", ipCidr, ipCidr.GetFirstValidIp())

	fmt.Printf("accroding to ip cidr %s, last valid address: %+v\n", ipCidr, ipCidr.GetLastValidIp())

	fmt.Printf("accroding to ip cidr %s, we can get random contained ip: %+v\n", ipCidr, ipCidr.GetRandomValidIp())

	ipCidr = ip_tools.GetRandomIpCidrV6()

	fmt.Println("Get a random ip cidr v6: ", ipCidr)

	fmt.Printf("accroding to ip cidr %s, network address: %+v\n", ipCidr, ipCidr.GetNetworkAddress())

	fmt.Printf("accroding to ip cidr %s, broadcast address: %+v\n", ipCidr, ipCidr.GetBroadCastAddress())

	fmt.Printf("accroding to ip cidr %s, first valid address: %+v\n", ipCidr, ipCidr.GetFirstValidIp())

	fmt.Printf("accroding to ip cidr %s, last valid address: %+v\n", ipCidr, ipCidr.GetLastValidIp())

	fmt.Printf("accroding to ip cidr %s, we can get random contained ip: %+v\n", ipCidr, ipCidr.GetRandomValidIp())

}
