IP Math anyone?

Hi Timothy,

for teaching I made a class for this.

you can instantiate it with a=ip('192.168.0.254/24') or 
a=ip('192.168.0.254','255.255.255.0') just using a=ip('192.168.0.254') 
would assign a appropriate subnet mask for this class (class B results in 
/16 or 255.255.0.0)

Since IP-adresses are only 32bit non signed integers, they are internally 
represented
like that.
If you make a class like that you can simply add the support to add 
integers to
it according to the subnet-mask you use.

Regards
Tino
