NetworkInterfacesView is a small and simple tool which displays detailed information on all your network interfaces, both active and inactive.
The program lists both the device and connection name, for instance.
It provides all the key address details (IP address, subnet mask, default gateway, and name server).
And there's plenty of other information. The MAC address and MTU values could be particularly useful, for example; the instance ID and interface GUID may be handy for low-level troubleshooting; and you get extra details that we're not quite so clear about. "Registry Time" is presumably the time when the particular network interface Registry key was last written or amended, for instance, and perhaps the idea is this might tell you when an adapter was installed. Our test PC displayed later dates in every case, though, so we're not quite sure how to interpret that.
Still, NetworkInterfacesView does provide a great deal of data which could be very helpful when you're troubleshooting network issues. As usual with NirSoft tools, this information can be exported as a report for analysis later. And the program itself is a tiny (56KB) portable executable which should run on any edition of Windows, from 2000 through to 8 (and both 32 and 64-bit).
We're not entirely sure how to interpret all the details here, but NetworkInterfacesView does display plenty of genuinely helpful information, and it'll make a great addition to your network troubleshooting toolkit.
