Aggregating US and Canadian Networks

Canada and the United States comprise nearly 50,000 networks and 1.7 billion public IP addresses. Aggregation of these networks will substantially reduce the size of your Access Control Lists.

As of today, November 30, 2011, through network aggregation, joining contiguous networks in the United States and Canada, we can reduce the size of this ACL by approximately 90%, down to 4,750 network range blocks.

Aggregation lessens the strain on your hardware and software resources.

As a courtesy we are including the aggregation of United States and Canadian IPv4 networks (in network range format) below.
