Does represent the same range as

Szymon Marczak asked:

The range of is -
The range of is -

AFAIK, ( - is not usable. So, do these represent the same range practically?

ip route add dev eth1 # 1
ip route add dev eth1 # 2

Is the effect the same?

My answer:

Clearly these are not the same.

However, nothing in is a valid destination address, so the effect of each route would be the same. Attempts to connect to anything in would just fail as always with an Invalid argument error, while attempts to connect to would be routed as specified.
