Powershell IP 地址范围
Powershell IP address range
我需要帮助我用 Powershell 编写的代码。程序应生成范围内的 IP 地址。例如从 10.4.254.250 到 10.4.255.255.
当我有相同的子网时（从 10.4.255.x 到 10.4.255.x），一切都是正确的。当我有不同的子网（从 10.4.254.250 到 10.4.255.255）时，问题就开始了。
输出无效。请试一试。谢谢你的帮助。
正确的输出应该是，10.4的ip地址。255.X从1开始。现在从250开始到255。
我需要获取从变量 $from 到变量 $to 的所有 IP 地址。当 IP 地址在同一子网时 $from = "10.4.255.1" $to = "10.4.255.1" 都是正确的。问题开始了，当不同的子网 $from = "10.4.254.250" $to = "10.4.255.255"
看下面我的代码：
$from = "10.4.254.250"
$to = "10.4.255.255"
$Ip_Adresa_Od = $from -split "\."
$Ip_Adresa_Do = $to -split "\."
foreach ($Ip_Adresa_A in $Ip_Adresa_Od[0]..$Ip_Adresa_Do[0])
{
foreach ($Ip_Adresa_B in $Ip_Adresa_Od[1]..$Ip_Adresa_Do[1])
{
foreach ($Ip_Adresa_C in $Ip_Adresa_Od[2]..$Ip_Adresa_Do[2])
{
foreach ($Ip_Adresa_D in $Ip_Adresa_Od[3]..$Ip_Adresa_Do[3])
{
$Ip_Adresa_Pocitace = "$Ip_Adresa_A.$Ip_Adresa_B.$Ip_Adresa_C.$Ip_Adresa_D"
$Ip_Adresa_Pocitace
}
}
}
}
错误的输出是：
10.4.254.250
10.4.254.251
10.4.254.252
10.4.254.253
10.4.254.254
10.4.254.255
10.4.255.250
10.4.255.251
10.4.255.252
10.4.255.253
10.4.255.254
10.4.255.255
您必须将您的 IP 地址转换为整数，然后在 for 循环的每次迭代中将整数转换为字节数组：
$from = "10.4.254.250"
$to = "10.4.255.255"
$Ip_Adresa_Od = $from -split "\."
$Ip_Adresa_Do = $to -split "\."
#change endianness
[array]::Reverse($Ip_Adresa_Od)
[array]::Reverse($Ip_Adresa_Do)
#convert octets to integer
$start=[bitconverter]::ToUInt32([byte[]]$Ip_Adresa_Od,0)
$end=[bitconverter]::ToUInt32([byte[]]$Ip_Adresa_Do,0)
for ($ip=$start; $ip -lt $end; $ip++)
{
#convert integer back to byte array
$get_ip=[bitconverter]::getbytes($ip)
#change endianness
[array]::Reverse($get_ip)
$new_ip=$get_ip -join "."
$new_ip
}
使用 IP 地址和范围很复杂，如果我正在使用的 program/software 已经做到了，我会尽量避免这样做。这是我前段时间写的一些函数，可以将地址转换为十进制值，这样更容易操作。可能有比这更好、更精确的解决方案，但它也会 return 基于具有子网地址或 CIDR 掩码的地址的范围。它还应涵盖提到的 @vonPryz 情况，其中地址跨越 .24 CIDR 范围。
function Find-IPRange {
<#
.SYNOPSIS
Determines all the IP address in a given range or subnet.
.DESCRIPTION
This function can evaluate a set of addresses based of the following three options:
Range - What IP addresses are between this and that address
Mask - What are the IP addresses given a particular IP address and mask, i.e. 24, 25.
Subnet - What are the IP addresses given a particular IP address and subnet address, i.e 255.255.0.0, 255.255.255.192
You have to specify an IP address to use the subnet and mask options. For the range you have to specify two addresses.
.PARAMETER Start
Start address of an IP range
.PARAMETER End
End address of an IP range
.PARAMETER IP
Any valid ip address
.PARAMETER Subnet
A valid Subnet IP address i.e. 255.255.255.0, 255.255.0.0
.PARAMETER Mask
A valid net mask from 0 to 32
.EXAMPLE

I hope I understand your question. I believe you would like to restart the counter on the 4th octet back to 1 once the 3rd octet iterates from 254 to 255? There's probably a better way to do this but for now hopefully this works. I've added an if statement that resets the range once the final 10.4.254.255 ip is reached. This will allow your loop to include the 10.4.255.x range starting from 1 in the 4th octet until 255 is reached. The while loop condition will be set to false once the final 10.4.255.255 IP is reached and exit.
I hope this helps and provides the desired result.

I hope I understand your question. I believe you would like to restart the counter on the 4th octet back to 1 once the 3rd octet iterates from 254 to 255? There's probably a better way to do this but for now hopefully this works. I've added an if statement that resets the range once the final 10.4.254.255 ip is reached. This will allow your loop to include the 10.4.255.x range starting from 1 in the 4th octet until 255 is reached. The while loop condition will be set to false once the final 10.4.255.255 IP is reached and exit. I hope this helps and provides the desired result.
