Duncan,

        Yes, the most specific network statement determines which area
an interface will be in. For example, the below configuration dictates
that interface 10.10.10.10 will be in area 3:

Router ospf 1
 Network 10.0.0.0 0.255.255.255 area 0
 Network 10.10.0.0 0.0.255.255 area 1
 Network 10.10.10.0 0.0.0.255 area 2
 Network 10.10.10.10 0.0.0.0 area 3

        In previous versions it used to be the order in which the
statements were entered in. In newer versions the IOS automatically
reorders it the way it wants, so the most specific statement wins.

HTH,
