About IP Ranges
IP Range
An IP range is a contiguous block of IP addresses defined by a start and end address. It can often be represented by one or more CIDR blocks.
CIDR Aggregation
CIDR aggregation is the process of combining valid adjacent network blocks into a single larger block, or representing a range as a minimal set of CIDR blocks.
