I just had one of our customers turn in two class B addresses in exchange for 130 C's. I'll make the trade,because it allows me to chunk the whole CIDR block as a single entry, instead of two disconnected B's. Two observations: 1. The NIC ought to take a stonger position to refer requests to folks with allocated CIDR blocks. I have had four sites turn in individual C's for numbers from our block. 2. Once folks know this is possible, and works well, these numbers vanish. Perhaps this is only because we are working with state agencies who are building internal networks. -- Regards, Bill Manning bmanning@rice.edu PO Box 1892 713-285-5415 713-527-6099 Houston, Texas R.U.
