Determining IP Address of Network Adapter 3/20/2008 10:35:09 AM

How do you determine which IP Address is bound to which NIC card in a mult-honed machine ?

Recently I ran into the task of ensuring the nic cards on our Clustered machines were all named with the standard "Private" and "Public" as opposed to various things like "network adapter 1" etc.

All our Private nics in the cluster start with 192.x.x.x.  So to ensure I was naming them properly I needed to find what IP address was bound to "network adpater 1" etc.  This seems easy but for some reason took me a while to figure this out.

( and if you look carefully in this example you will see the current nic card labeled "admin" has a public IP Address, someone goofed ! and reversed them, so this is important stuff to know how to check !)

We found two ways to do this, through windows control panel, and through our vendor's nic card configuration utility (HP).

Select Start -> Control Panel -> Network -> {Adapter Name} than right click and select status.

From the Status properties window you can select the "advanced" tab and determine which IP Address is bound to this adapter.

Our particular Vendor is HP, and from the HP Network Utility you can select a NIC Card and then choose, Information, and in the Details section you can find the IP Address.
