Any IP Range to (one or more) CIDR Blocks

[forger]

does anyone know how to convert a random/any ip range to as much cidr blocks necessary?

there's ought to be some processing with a while loop but i just don't know how to process it.

the idea is to make the ip into 4 binary octets and start comparing values :S but.. that's just about it from me

Example: 76.0.0.1-85.0.2.50 into as much cidr blocks necessary (that'd be the result)

Any ideas are welcome
