How to create multiple (hundreds) IP address using script in single Windows Server VM

[albertwt]

Hi All,

I'd like to perform database application transactional and concurrent load testing which requires approx. 100 IP address in a single host (Windows Server 2003 box) so that one NIC can have multiple IP address.
Is there any quick way (Powershell / NetSH) to create those IP address in one single box ?

example:

VM-Simulator1 - 10.2.1.1

10.2.1.2
10.2.1.3
10.2.1.4
10.2.1.5
.
.
.
10.2.1.102

VM-Simulator2 - 10.2.2.1

10.2.2.2
10.2.2.3
10.2.2.4
10.2.2.5
.
.
.
10.2.2.102

i know how to do it in Windows Server 2003 manually one by one but that's too daunting to do it manually.

Thanks.

Does this help - To add a bunch of IP addresses to a network connection without having to type each one in individually

Finally I've found what I've been looking for:

#setup collection of IP address strings, include original IP
$ips = 1..100 | %{ "10.2.1.$_" }

#also subnet masks, need as many as IP addresses
$masks = 1..100 | %{ "255.255.255.0" }

#get the NIC
$nic = Get-WMIObject win32_networkadapterconfiguration -computer VM-Simulator1 | where { $_.IPAddress -contains "10.2.1.1" }

#set addresses
$nic.EnableStatic($ips,$masks)

hope this can be helpful for everyone in this forum.
