"0.0.0.0" is very different from "0.0.0.0/0".
The first means "one specific IP address, which you will never find on a real
device".
The second means "any IP address at all".
The reason is simply because if you do not specify a netmask, /32 is assumed,
which means all bits must match exactly. On the other hand /0 means that no
bits have to match at all (which is why 0.0.0.0/0 corresponds to all
addresses).
