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.
