I would like to get comments regarding the problems of using multiple
class 'C' addresses vice a single class 'B' addresses.  Obviously
this is an issue because the NIC is hesitant in granting the rapidly
diminishing number of class 'B' addresses.

We intend to have approximately 2000 IP addresses with typically 50
address per sub-net.  Using class 'C' address we are looking at 40 sub-
nets or approximately 10 'C' addresses.

Questions:

1)  What kind of management problems will we run into if we use class
'C' vice 'B'?  It seems to me that use of multiple class 'C' addresses
would not change the number of routers required - the number of sub-nets
dictates that.

2)  Someone mentioned that linking up a bunch of 'C' addresses will
require the use of some external gateway protocol (make sense - we need
to route between class 'C' networks) on our routers.  Is this a big
deal?  Is EGP a feature only available on expensive routers?

3)  Are there any advantages to getting a contiguous set of class 'c'
addresses (e.g. 192.101.190,191,192, . . . etc)?

4)  Would there be any problem in implementing a single domain name
DNS over multiple class 'C' addresses?

Thanks.
