It is probably not that simple.

Microsoft have a bad habit of "assuming" a subnet mask where one is not
specifically available. Worse still the behavior may vary between different
versions of MS Windows (especially, but not limited to NT and Win9x).

To be safe it is best to stick to classful network addresses when there is
any change that MS may assume a subnet mask e.g. PPP.

That assumption requires that the PPP peer's IP address should be on the
same class (C) subnet as the client, i.e. the RAN's IP address should be in
the same class C network as the IP address given to the DSL user. Win2k will
use the client IP address as a default gateway, Win98 uses the RAN's IP
address as a default gateway and sometimes gets upset when the two are in
different classful subnets.

Break the above rules and suddenly you start seeing weird and wonderful
sometimes works, sometimes doesn't scenarios.

Cheers

BG.
