"Configured" networks/prefixes are those which are included in the NSFNET/ANSnet backbone configuration files, and is a subset of all "registered" networks. The number of networks/prefixes in the active routing tables is a subset of the configured networks/prefixes. The As are networks/prefixes with 8-bit masks, the B are are networks/prefixes with 16-masks, and the Cs are networks/prefixes with 24-bit masks. The Aggs are CIDR blocks of networks/prefixes with other length masks. The "added networks" and "deleted network" lines indicate the changes since the previous report, which is 3 or 4 days. The configured networks table is updated twice a week.
