Converting an IP range to CIDR notation
Does any one have Java code for converting a given range of IP
addresses to CIDR notation, like the one here http://ip2cidr.com/.
Thanks.

You may have a look at the Apache JAMES project, it seems that they
provide such converters :

Would this work for you?

Nope. Not going to work either.

Hi, Sai.
In that same package, there's a CIDRIterator class that may do the trick.
I'll take a look at let you know.

Does not look like it. What I'm looking for is - given a from and to
IP addresses, it needs to generate corresponding Subnets using the
CIDR notation. So, for example, if the from address is 192.168.1.1 and
the to address is 192.168.1.12, the subnets should be -
192.168.1.1/32
192.168.1.2/31
192.168.1.4/30
192.168.1.8/30
192.168.1.12/32
I downloaded the source code of Apache James too, and did not find
anything that would do this.
