	Yes, They have the same subnet mask and network address

	Their can be problems cause by this kind of setup but it all depends on
whether this is a test setup at home or a real scenario at work in a
large network.


	From a strategic point of view I would always advise against more than
a class c in one broadcast domain, this means that you should either put
them on different switches bounded by a router or use a single switch
with multiple vlans and again bound them with a router.

	Switches are higher performance devices which can be managed and
controlled so I would have to ask again whether you are doing this at
home or in a large scenario at work.
