What impact, if any, will having a /32 netmask on an aliased IP have? It seems inconsistent with networking practice regarding interface aliases, which typically view the aliased IP's simply as distinct hosts on the same physical network, allowing them to have the same netmask. This method is used with Cisco IOS and other Unix-like operating systems. Is it incorrect?
