NOTES:
This report is a listing by month of the number of networks
configured for announcement on the NSFNET infrastructure.
It includes a breakdown by IP class and the number of
non-US nets.
Network IP addresses have historically been grouped into
three classes: A for IPs 1-126, B for 128-191, and C
for 192-254. With the advent of CIDR blocks in March
1994, the classes have been re-labelled according to
the corresponding prefix length. The "Other" column
is used for networks using prefixes other 8, 16, or 24.
Prior to December 1992, the sum of the values in the Prefix
Length columns will not usually add to the total. The
difference represents deleted networks for which we no
longer have enough information to determine their class.
Counts exclude networks that are configured for the ANSNet
backbone but are not routed by NSFNET.
