iprange

这是一个通过给定IP范围字符串生成IP集合的工具.

This is a tool for generating IP SETS from a given IP range string.

Use as a library

import: import "github.com/XinRoom/iprange"

Simple to use:

package main

import "github.com/XinRoom/iprange"
import "fmt"

func main() {
	ipSet, err := iprange.GenIpSet("1.1.1.1/30")
	if err != nil {
		fmt.Println(err)
		return
	}
	fmt.Sprintln("1.1.1.1/30 GenIpSet is %s", ipSet)
}

Iterator (Save memory) 迭代器（省内存）:

package main

import "github.com/XinRoom/iprange"
import "fmt"

func main() {
	it, startIp, err := iprange.NewIter("1.1.1.1/30")
	if err != nil {
		fmt.Println(err)
		return
	}
	for itn := startIp; it.HasNext(); itn = it.Next() {
		fmt.Println(itn)
	}
}

GetIpByIndex (For random IP and progress) 通过索引获取IP（可用于乱序IP生成和进度恢复）:

package main

import "github.com/XinRoom/iprange"
import "fmt"

func main() {
	it, _, err := iprange.NewIter("1.1.1.1/30")
	if err != nil {
		fmt.Println(err)
		return
	}
	for i := uint64(0); i < it.TotalNum(); i++ {
		fmt.Println(it.GetIpByIndex(i))
	}
}

Contains 判断IP是包含于对应IP字符串:

package main

import (
	"github.com/XinRoom/iprange"
	"net"
)
import "fmt"

func main() {
	it, _, err := iprange.NewIter("1.1.1.1/30")
	if err != nil {
		fmt.Println(err)
		return
	}
	fmt.Println(it.Contains(net.ParseIP("1.1.1.1")))
}
