Machine does not respond to "additional IP"

Gurus,

In the advanced TCP/IP properties of a Windows system, I noticed you can
assign it additional IP addresses. What is this for, exactly? I entered an
additional IP there and it doesn't respond when I ping it from a remote
machine. Only the primary IP responds.

Hello Spin,

Sometimes you have multiple ip addresses for webservers for example. But
better describe what you are trying to achive and then we can see how to
help you. By default always one ip address is enough.

Best regards

It allows you to add IP addresses, whether on the same subnet as the default
IP, or on another subnet. However, if you add an IP that is not on the same
subnet as the default IP configuration, you cannot ping it from a remote
subnet because the default configuration's gateway is used, therefore it
cannot respond.

I use this feature when I need to connect to and administer devices or other
machines on a different IP. For example, when I setup a Cisco ASA or PIX for
a customer, I know the default IP of the device is 192.168.1.1, however my
workstation has a static configuration on a totally different subnet. I then
add 192.168.1.10 to my IP configuraiton as an extra IP, so now I can connect
to the device to set it up, change it's IP, etc. If I change the IP on the
PIX to a range on their own subnet, then I must make sure I add an IP on the
same subnet of the new address on my workstation so I can re-connect to it.
After I am done, I shut down the device and remove the IPs from my
workstation.
