> man 5 hosts_access
... snip ...
An expression of the form 'n.n.n.n/m.m.m.m´ is interpreted as a
'net/mask´ pair. An IPv4 host address is matched if 'net´ is equal
to the bitwise AND of the address and the 'mask´. For example,
the net/mask pattern '131.155.72.0/255.255.254.0´ matches every
address in the range '131.155.72.0´ through '131.155.73.255´.
Is there any reason why it must be written out as:
131.155.72.0/255.255.254.0
... as opposed to using the shorter version:
131.155.72.0/23
