some go tools for my develop

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

package main

import (
	"fmt"
	"github.com/zhuliquan/go_tools/ip_tools"
)

		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)
