I am connecting a small number of PC's to the department-wide ethernet cable. There are no more addresses left in the class-c subnet assigned to that cable (128.97.64.nnn) so we have gotten a second class-c subnet (128.97.20.nnn). The question is: Must I join the new PC subnet to the department ethernet using a router or can I just use a bridge? Will outside internet routers get confused if there are two subnets on the same ethernet cable? Another twist is that we will actually be sharing the new address space with a group on a different floor. Both groups have access to the department ethernet cable, but the connection from one group to the other would require a long cable parallel to the existing cable. Thus, if both groups just bridges off of the main cable, there is no problem. If, however, a router is required, it seems as if this address-sharing will not work unless we link the two groups after the router. Thanks for any information, Mike McCarrick mmccarrick@uclaph.physics.ucla.edu
