We have a class B internet address and want to use 10 bits for subnets and 6 bits for host addresses (for reason too complicated to explain here). We set our subnet mask to 0xffffffc0 under SUN-OS4.0. However, when we added the route using e.g /usr/etc/route add 128.189.62.64 128.189.62.2 1 the routing table indicated that the route is to the specific host rather than to the subnet. Host 128.189.62.2 can't send to host 128.189.62.65, which I thought is on the same subnet as 128.189.62.64. Am I doing something wrong? BTW, is it possible, under SUN-OS4.0, to have different subnet masks on 2 different ethernet interfaces on the same host? I.e. Can I use 0xffff0000 on ie0 and 0xffffffc0 on ie1?
