A Cisco will take all the addresses except the 0.x.x.x and 255.x.x.x
addresses, assuming that you don't use a mask that makes the address either
subnet or broadcast address.

OK, Tom. Now let's say single host assignments (/32 subnets) are not
allowed.
Now what... ?? Are your choices still valid?
(There is a point here...)

Nope. All of the addresses (with exception of 0.X.X.X and 255.X.X.X)
remain valid with a 32-bit subnet mask. I am testing on a loopback after
all... :)

Tom,
Consider the following requirement to put a spin on things: "There can
exist no subnet mask less than 24 bits".
Now what do you think? Does your answer change?
Ken

On a Cisco router the following work (tested on a loopback interface).
I've also included a subnet mask since the "default" classful subnet
mask won't necessarily work.
1.1.1.1 255.0.0.0
1.0.0.0 255.255.255.255
1.255.255.0 255.0.0.0
1.0.0.255 255.0.0.0
10.255.255.255 248.0.0.0
These don't work for obvious reasons:
0.45.34.23
255.223.234.24

Quiz question for the day:
How many of the following are possible valid, addressable IPv4
addresses:
1.1.1.1
0.45.34.23
1.0.0.0
1.255.255.0
1.0.0.255
255.223.234.24
10.255.255.255
Good luck to all!
Ken
