- 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.
