range2cidr
De-aggregates an IP address range into a list of network prefixes (CIDR blocks)
Returns a list of prefixes (CIDR blocks) that covers the given IP range.
For example, if:
ipLo = 23.128.1.0
ipHi = 23.128.7.255
then Deaggregate(ipLo, ipHi) will return:
23.128.1.0/24
23.128.2.0/23
23.128.4.0/22
