I'm not entirely sure what you're saying, but in general the answer is
yes, it is possible for different computers on the same ethernet to have
different network numbers and/or netmasks. The result is probably not
what you want, though, unless you are intentionally trying to interfere
with the free communication of all hosts on the ethernet. (for example,
you might be renumbering your network, and you want IP's on both networks
to work while you switch over, so you assign the networks different
numbers and have someone route between the two 'virtual' networks on the
same ethernet!) Or maybe you want to give some computers on the network
restricted access to the internet, and other ones completely free access,
but you want it all to be on one physical ethernet segment (maybe you are
using 10Base2, or your LAN is very large and you don't want to duplicate
the physical network through the whole building). So you do the same
thing and let your router sort it all out.
So yes, there are valid reasons to do this, but only in special cases.
You can't just give your computers random netmasks and hope everything
works, though. :)
