一开始打开github，一看是.net代码，一脸懵。第二天起来于心不甘，就想试试能不能根据代码逻辑以及函数名称分析一波算法。于是做了一波曲折但有趣的研究。现在将工具分享出来，希望能帮到大家，特别是需要处理大批量IP段或者内网时。其中研究的过程也可供各位师傅茶余饭后”取个乐子”。

二、工具介绍

github地址： https://github.com/foryujian/ipintervalmerge

功能：上面的图片中冰尘师傅已经说的很清楚了，不再多言。

三、什么是区间合并

（引自御剑师傅的github）

IP合并区间就是把重叠的IP段进行扩充，比如以上结果经过合并处理后变成:

四、各部分功能浅析

可以添加QQ群1004391443，有飞机大战、颜值打分器、打砖块小游戏、红包提醒神器、小姐姐表白神器等具体的实训项目，有清晰源码，有相应的文件

首先说明一点，我不懂VB.NET，在寻求各方的“支援”无果后，就自行按照单词的本身含义+百度来理解的代码，其中如有错误，请各位师傅不吝赐教。其次，这个浅析针对的是 https://github.com/foryujian/ipintervalmerge/blob/master/IP区间合并工具/IP区间合并工具/IP区间合并工具.vb ，而不是 https://github.com/foryujian/ipintervalmerge/IP区间合并工具/IP区间合并工具/bin/Debug/IP区间合并工具.exe 。这两个的算法是有差别的，我会在后文中给出。

4.1 读取文件中的IP地址类型

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">For Each txt In IO.File.ReadLines(file)
...
If txt.Contains("-") Then
...
ElseIf txt.Contains("/") Then
...
Else
...
End If
Next
</pre>

CIDR形式：192.168.0.0/24

包含分隔符形式：192.168.1.2-192.168.1.6

单个IP形式：192.168.1.1

4.2 IPToLong

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">Public Shared Function IpToLong(strIP As String) As Long
Try
Dim ip(3) As Long
Dim s As String() = strIP.Split(".")
ip(0) = Long.Parse(s(0))
ip(1) = Long.Parse(s(1))
ip(2) = Long.Parse(s(2))
ip(3) = Long.Parse(s(3))
Return (ip(0) << 24) + (ip(1) << 16) + (ip(2) << 8) + ip(3)
Catch ex As Exception
Return 0
End Try
End Function
</pre>

将点分十进制格式表示的IP转换成二进制形式表示的IP

算法描述：

先将点分十进制格式表示的IP以.来分成4部分。（e.g.:192.168.1.2 —>>192、168、1、2）第一段左移24位，第二段左移16位，第三段左移8位，第四段原样保留。（e.g.:（192<<24)+(168<<16)+(1<<8)+2即二进制形式表示的IP)

4.3 处理文件中的IP区间

intervals存放处理结果。

CIDR形式的处理：

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">tmp = txt.Split("/")
If tmp.Length = 2 Then
Dim ip1 As String = tmp(0)
Dim ip2 As String = tmp(1)
tmp = ip1.Split(".")
For x As Integer = 0 To 3
ip(x) = Integer.Parse(tmp(x))
tmp(x) = Convert.ToString(ip(x), 2).PadLeft(8, "0")
Next
Dim BitString As String = String.Join("", tmp)
BitString = BitString.Substring(0, CInt(ip2)).PadRight(32, "1")
i = 0
For x As Integer = 0 To 31 Step 8
tmp(i) = BitString.Substring(x, 8)
ip(i) = Convert.ToInt32(tmp(i), 2)
i += 1
Next
ip2 = String.Join(".", ip)
st = IpToLong(ip1)
ed = IpToLong(ip2)
intervals.Add(New Interval(st, ed))
End If
</pre>

算法描述：

以”/”将CIDR形式表示的IP地址分隔成两部分：tmp[0],tmp[1]。

将第一部分的IP地址以”.”分成4部分。

每一部分表示成8位二进制形式，不足的左边用0填充。然后将这4个部分连接起来。

将连接后的字符串从开始处截取tmp[1]长度的子串，然后在右边用1填充至32位。

在intervals中添加tmp[0]的二进制表示形式（即调用IpToLong函数）和第4步中的处理结果。（e.g.:192.168.0.0/24 —>>intervals中会添加”11000000101010000000000000000000″和”11000000101010000000000011111111″）

包含分隔符形式的处理：

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">tmp = txt.Split("-")
If tmp.Length = 2 Then
st = IpToLong(tmp(0))
ed = IpToLong(tmp(1))
intervals.Add(New Interval(st, ed))
End If
</pre>

算法描述：

以”-”将其分成两部分。

在intervals中添加这两部分的二进制表示形式。（与上面CIDR形式的处理情形类似，不再举例。）

单个IP形式的处理：

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">intervals.Add(New Interval(IpToLong(txt), IpToLong(txt)))
</pre>

算法描述：在intervals中添加两个一样的单个IP的二进制表示形式。（为了方便下面的Merge函数处理。）

4.4 LongToIP

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">Public Shared Function LongToIP(longIP As Long) As String
Dim sb As New StringBuilder
sb.Append(longIP >> 24)
sb.Append(".")
sb.Append((longIP And &HFFFFFF) >> 16)
sb.Append(".")
sb.Append((longIP And &HFFFF) >> 8)
sb.Append(".")
sb.Append((longIP And &HFF))
Return sb.ToString()
End Function
</pre>

将二进制形式表示的IP转换成点分十进制格式表示的IP

算法描述：

二进制形式表示的IP右移24位。二进制形式表示的IP与0XFFFFFF做与运算后右移16位。二进制形式表示的IP与0XFFFF做与运算后右移8位。二进制形式表示的IP与0XFF做与运算。将上面4部分及每次计算后连接的.拼接起来即点分十进制表示的IP，返回。

4.5 Merge

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">Public Function Merge(ByVal intervals As List(Of Interval)) As List(Of Interval)
Dim res As New List(Of Interval)
If intervals.Count = 0 Then Return res
intervals = intervals.OrderBy(Function(i) i.st).ToList
res.Add(intervals(0))
For i As Long = 1 To intervals.Count - 1
If intervals(i).st <= res(res.Count - 1).ed Then
res(res.Count - 1).ed = Math.Max(intervals(i).ed, res(res.Count - 1).ed)
Else
res.Add(intervals(i))
End If
Next
Return res
End Function
</pre>

这应该算是核心部分了，将IP区间合并。

算法描述：

将intervals中各个区间按起始IP升序排列。在res中添加intervals的第一个区间。（res作为最后的处理结果返回）将intervals中从第二个区间开始的每个区间的起始IP与res中最后一个区间的结束IP作比较，如果小于或者相等，则将intervals中该区间的结束IP与res中最后一个区间的结束IP中的较大值赋给res中最后一个区间的结束IP。如果大于，则将intervals中的该区间直接添加到res中。

4.6 输出合并结果

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">For Each item In IPRes
If item.st <> item.ed Then
appstr.AppendLine(LongToIP(item.st) & "-" & LongToIP(item.ed))
Else
appstr.AppendLine(LongToIP(item.st))
End If
Next
</pre>

这一部分就是将合并后的结果输出：如果起始IP与结束IP不同，则以包含分隔符的形式输出；如果相同，则只输出起始IP。

五、IP区间合并工具.vb较exe改进部分

一开始只把exe文件下载下来试了试效果，但是在有192.168.0.0/26时，结果是0.0.0.0。（打码有点丑，见谅。）

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555915256271" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;">

用ILSPY反编译后可以看到：

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555915256273" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;">

exe版本只能处理/8、/16、/24、/32的CIDR形式的IP地址，这也就是为什么在有192.168.0.0/26时，结果是0.0.0.0了。改进部分如下（可以回看0×04.3）：

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">BitString = BitString.Substring(0, CInt(ip2)).PadRight(32, "1")
</pre>

运行效果如图：

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555915256284" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;">

image

不足之处在于192.168.0.0，在.exe中是直接拼接的”.1″，所以结果是192.168.0.1。

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555915256288" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;">

我的Python脚本中对这一部分做了调整。

六、编写Python脚本实现相同功能

将主要部分main函数放出来，其他的函数部分根据上面的算法可以自行写出：

其中oldpath是合并之前的IP区间存放的文件路径。

七、后记

这个工具在需要处理大量IP段（如：一个市级IP段或成批自动化扫描）时很有用处，而且会减少后面的工作量。感谢gx童鞋帮我调试这个工具（因为我本地没有VS）。
