I have a machine that has 4 virtual hosts besides its main IP address. My arp cache seems to be full of entries that should not be there. My machine is on subnet aaa.bbb.ccc and it has a default route to aaa.bbb.ccc.1 as its gateway. This means to me that the only arp entries in my cache should be for machines on aaa.bbb.ccc. Instead I have those entries plus entries for aaa.bbb.sss aaa.bbb.xxx, etc... All the entries are inside my org's class B address aaa.bbb, but should they not be restricted to my subnet as well?
