Prolog CIDR IP Matching

[Felix Schmidt]

Hi,

I'm new to prolog. I have a questions for you experts. I was using google already, but haven't found a solution yet.

I want to do CIDR matching in Prolog.

Basically what I would like to do is the following:

cidr(10.0.0.0/24)

ip(10.0.0.1) -> How can I check that this IP is a match based on the CIDR?

ip(10.0.1.1) -> This IP would be no match.

Thanks

- felix

This isn't really the Prolog thingy as it is mostly bit manipulation,
but it can (of course) be done. See
