I believe that is why Cisco has the statement:
ip subnet-zero
So the address will work in a Cisco router, but not necessarily in
another's router.

Please respond to

10.0.0.254/24 is considered bad form as the subnet portion of the IP
address is all zeros....
Given a class-A network with a /24:
255.0.0.0 network portion
0.255.255.0 subnet portion
0.0.0.255 host portion
and so
10 - network
0.0 - subnet
254 - host
Notice that the subnet is all zeros... bad.
