IPNetwork 1.2 Activator Full Version

The IPNetwork application was developed to be a small command line utility which will take care of complex network, ip, netmask,  subnet, cidr calculation. It works with IPv4,

it is written in C# and has a light and clean API and is fully unit tested.

Usage:

ipnetwork [-inmcbflu] [-d cidr|-D] [-h|-s cidr|-S|-w|-W|-x|-C network|-o network] networks ...

Print options

-i : network

-n : network address

-m : netmask

-c : cidr

-b : broadcast

-f : first usable ip address

-l : last usable ip address

-u : number of usable ip addresses

Parse options

-d cidr : use cidr if not provided (default /32)

-D : use default cidr (ClassA/8, ClassB/16, ClassC/24)

Actions -h : help message

-s cidr : split network into cidr subnets

-w : supernet networks into smallest possible subnets

-W : supernet networks into one single subnet

-x : list all ipadresses in networks

-C network : network contain networks

-o network : network overlap networks

networks : one or more network addresses

(1.2.3.4 10.0.0.0/8 10.0.0.0/255.0.0.0 ...)
