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.
