Re: Windows: Don't try to save me, PLEASE

ARP requests are broadcasts
They do not cross routers
If the "adapter" is in a subnet by itself (reguarless of the mask) and there is
no router,... it will never recieve an ARP request to begin with. So give it a
normal mask.

IP#s have two purposes in the lives:
1. Provide a means to determine routes in a routing table. This is the
Network portion of the address.
2. Provide a means to determine the MAC address. This is the Host
portion of the address.

Traffic flows by the MAC address, not the IP Address,...that is a huge
misunderstanding by many if not most people. That is why ethernet networks are
called "ethernet" networks and why the MAC address is also called the "ethernet
address".

IP is "Internet Protocol",...it gets you from "Network to Network" where it is
then used to determine the MAC Address (via ARP) whch takes you from the Network
entry point to the Host. If both Hosts are in the same Network then the IP#
serves no purpose other than to determine the MAC address, ...it does nothing
else.

I know what I want...

I need to set an IP address on the MS Loopback device which will not
respond to ARP. The way to do this is to set a 32-bit subnet mask for
the IP address.

Windows is trying to "save" me from myself by keeping me from setting
the netmask to 255.255.255.255 ...

C:\>netsh interface ip set address "Loopback" static 10.0.0.100
255.255.255.255
255.255.255.255 is not an acceptable value for mask.

... yes, I know that under normal circumstances, there wouldn't be any
connectivity, but I know what I'm doing and this is the way to do it.
This is what I want. How can I force the value in there?
