Message-ID: <8806270548.AA23542@ucbvax.Berkeley.EDU> Date: 25 Jun 88 13:00:04 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 19 I attempted to post this question to the BIG-LAN discussion group about a week ago, but I think it got lost in transit. Anyhow, I apologize if you have seen this before. As we plan or campus network, we have decided to use 4 level domain names of the form: host.dept.MSSTATE.EDU. This seems to be in line with what a lot of other universities do. We also plan to assign internet addresses in a subnetted fashion even though initially we will be using MAC layer bridges instead of routers for traffic isolation. I am confused about the relationship of domains and subnets. Is there, or should there be, any specific relationship between domains and subnets? In particuar, is it possible to have a single domain that contains more than one subnet? Conversely, is it possible to have a single subnet that contains more than one domain? Can you have a single domain that is spread among several subnets? The situation I am wondering about is where a department is spread among several buildings on campus.
