Description

I have a list of IP ranges in this format:

112.0.0.0 / 112.0.0.255

e.g. start / stop

and I need it converted into this format:

112.0.0.0/8

Must be able to handle all cases, not just simple ones. e.g.

11.0.0.0/ 12.1.52.63
112.255.0.0/ 113.255.255.255

and so on.

To be delivered as an excel vba macro that takes two string parameters and returns one.

In order to perform this function, I would convert both set of four octets to binary numbers. To calculate the first address, I would AND the two sets of octets. To calculate the second address, I would AND the first address with the NOT of the second address. For example 11.0.0.0/ 12.1.52.63 would be converted to 8.0.0.0 / 3.0.0.0. This process would be automated with VB code to perform the logical comparisions binary numbers.
