Powershell Extract ip's from string

Question

I would like to get from the user 2 variables: $ip1 $ip2

and run a loop between their IP address. for example:

$ip1 = 192.168.1.10   
$ip2 = 192.168.1.200

The script assume its a class C, the i need to strip everything and get 3 variables:

$IP = 192.168.1.
$FirstIP = 10
$LastIp = 200

At first i thought about substring ($ip.length - 3), that could give me XXX, .XX, X.X (Where X is a number) Depends on the last Octat.. Any idea how can it be done nicely?

I personally like using -replace : '192.168.1.100' -replace '\.\d+$' — AdminOfThings

First: Thank you very much it works :), if its not trouble, can you translate to words what it means: '\.\d+$' ? — Shahar Weiss

Yes. It is regex match for literal . (\.) and a digit (\d) one or more times (+) followed by end of string ($) — AdminOfThings

You could split the string by dot and use range operator to create an array from last elements:

$ip1.Split('.')[-1]..$ip2.Split('.')[-1] | foreach{$_}
