There is no difference if there is only 1 interface within the 1.1.1.0
255.255.255.0 subnet range. By using 0.0.0.0 you are specifying a very
specific network /32 interface to be part of OSPF, by using a wider range
/24 you can let that include more than 1 network.
It will still advertise the 1.1.1.0 ip address as a /24, even if you
specified 0.0.0.0
