How to add Multiple IP Address in Windows 2000,XP,2003

Written by

Sometimes, there is a need to have more than one IP Addresses assigned to a PC or a Server. If you have multiple services running on a server like a webserver and a mail server and want to assign each of these services seperate IP Addresses the Multiple IP addresses will help. While this need not necessarily require to have more than one Network Interface Card (NIC) on the server.

You can add multiple IP Addresses to a single interface card. However, these IP Addresses should be in the same logical network although in different subnets.

The following procedure will just guide you how to add Multiple IP Addresses:

1. Open Control Panel and Network Connections.

2. Right-click the LAN connection and select properties.

3. Select Internet Protocol (TCP/IP) and click properties.

Windows Internet Protocol (TCP/IP)

4. Select "Use the following IP Address" and enter the primary IP Address, Subnet mask and Gateway and the primary and secondary DNS Servers.

Enter Primary IP Address, Subnet gateway and DNS Servers

5. Click Advanced then Add under IP Addresses.

6. Add the IP Address and Subnet mask. Repeat the procedure if there are additional IP Addresses to be added.

Add Multiple IP Address

7. Click Add under "Default Gateways" and add the gateway addresses.
NOTE: The system will always use the 1st available Gateway and will use the additional gateways unless the primary gateway is not reacheable.

Add Multiple Gateways

8.Click OK then OK and then OK to save the changes.

9. To confirm the multiple IP Addresses are set, from the command prompt (Start-Run and type CMD) run the ipconfig command. You can see multiple IP addresses on one Network Interface Card.

Thank you! I’ve been wondering how to do multiple IP addresses in windows. With gig-e NICs at home one is not likely to need the bandwidth or seperate physical ports.
Now, how do I get specific programs to use only the IP address that is intended for them?
Also, most any ethernet NIC one buys today proclaims it supports 802.1Q vlans, and my home cisco 2621 certainly does, but how do I get to configure them and use them in windows? I use them all the time on big routers and switches at work, it is just windows that is in or perhaps just is the fog cloud.
VLANS would also be useful for virtual machines especially if that is the only way one can get specific programs to use specific addresses.

802.1Q support is built into the NIC driver and most of them come with advanced configuration software. I’m Intel Pro cards & Broadcom cards do come wth the software with which you can add vlans IDs to it.

Do you know what the upper limit is officially for the number of IPs you can assign to a single adaptor? I think I have experienced that up to 4 work, but I was wondering if anyone has seen any official documentation on this.

I want to fix a logical IP address to a LAN card or MAC Address as if the user can never change IP settings. Please give me a solutions.

Not sure about your setup. But, you can setup a reservation on ur DHCP to ensure that the PC/laptop gets the same IP address and restrict the switchport to a particular vlan (based on the DHCP scope)

I did one to 7, but when I check in ipconfig, it lists all zeros. Would you happen to know why? And, what the fix is? Thanks.

Hi
If you define two IP on one network card, you can have trouble to register dynamically the second IP on the DNS database.
To do this, you need to create the MaxNumberOfAdressToRegister in the registry.
For more information, see http://msreport.free.fr/?p=96 (in french).

192.168.x.x indicates their LAN private IPs. Their public IPs with which they are seen on the internet is shown on the top of this webpage.

Hi,
Is there a way to set multiple IPs to a NIC using WMI APIs or netsh command? (I am able to do this using “netsh..add..”). Most importantly I wanted to know if there is a way to set an IP and identify it as Primary IP for the NIC.
Say I have ip1, ip2, ip3 to be set to NIC1 of which ip2 should be my primary IP – how do I control this?

Hi,
This is something that I have wanted to use for a long time. I am trying to use VB based tool and want to use different Physical IP each time.
If I add different Ip addresses as shown in above example, how can I keep suffling them to use different each time from the available list?
Awaiting your response!

Hi, my server is on DMZ side and I want to host two website on port 443 (SSL). It requires unique combination of IP address and port number. I created two IP address on same logical network although in different subnets. One website is working and the second is not. Do I need to do anything on my ASA firewall or CISCO switch?
Many thanks,

Dear sir,
I am really greatful to u for your help. My main IP is 192.168.120.160. There are more serial in my network like 192.168.111.x, 192.168.180.x and so on. But the problem is all the subnet masks are the same. SO when I combine several IPs cmd shows that but the problem is I lose the speed along with the main speed.In short me net becomes out of servie. It is not working in my pc. I think the problem is subnet mask that i have only one. What should I do…..Please tell me

Just one question regarding the sentence:
“these IP Addresses should be in the same logical network although in different subnets.”
Is there a problem to have more than one IP on the same NIC in the same subnet?

hi there,
how do i add a secondary ip if i already have a router connected to the server… the internet line is routed with a ADSL modem

We have Windows servers with more than 20 IP addresses on a single NIC (and several NICs, all of which happen to be virtual). The IP addresses can be in different subnets and have different classes (/8,/16,/24). Works fine. The main reason we do that is that these servers act as interface boxes in multi-(V)LAN systems and need to be reachable from different subnets which are otherwise isolated.

Hi
We are facing a slightly different problem than what you people are discussing here.
In our organization, there are over 700 users connected through LAN and/or Wifi through DHCP.when a particular user moves from LAN to Wifi or vise versa, He/She starts using two IP addresses. Even after disconnecting from either connections, the IP address doesnt gets released and so any other who has just connected wont get an IP.
(We are using 4 pools of IPs, which I am sure is more than enough for 700 users.)
Basically what we want is , as soon as a user moves from LAN to Wifi or Viseversa the old IP assigned to his system should be released for any other user.
Thanks in advance !

Hi
I also would like to know how to setup multiple IP Adresses in Windows 7 or XP.
Here is my situation ;
We have 3 different branches which is connected to our head office.
Each branch has a different IP Range
Head office IP Range is 192.168.30.0
Branch A is 192.168.33.0
Branch B is 192.168.0.0
Branch C is 10.0.0.0
The reason for multiple IP adresses is because when the CEO goes to his desk at all the different branches he plugs his lan cable to the laptop and doesn’t want to change the ip adress all the time. He wants that specific IP Adress which is assigned to him per branch on the laptop so that he is of the proxy and has full internet access.
Your help in this regard will be highly appreciated
You
