Me it is to convert an ip addresses like (192.168.2.1/24) into a 32
bits integer. Also the mask i wil convert to a 32 bit interger. Via
converting the 4 octets into its binary representation. Put all the 32
bits in a string and convert it to a interger. After that i can do an
AND between these two integers and calucate the network part of it. 

Wat i would like to have is a database of ip records. With ip number
and mask stored as an integer. This way i can lookup an ip addres in
the database and find out to wich (sub)network a.i. customer it
belongs....

Maybe i'm on the wrong track to solve my problem.....
