A package to retrieve information for a given ip and subnet

ip - A handy internet protocol address helper

This ip package will help you retrieve info for a given ip and subnet. Currently only supports ipv4. This package is written in vanilla cfml and requires no depencies

License

I dont know about licenses, do whatever you want.

Instructions

Just drop into your modules folder or use the box-cli to install

box install ip

Models

The module registers the following mapping in WireBox: ip@ip. Which is the class you will use to parse ip addresses and subnets. Currently this class supports one method, with two signatures.

• v4( ipAddress, subnetmask ) - Parse ip address with a given subnet mask
• v4( cidrString ) - Parse cidr signature.

E.g.

//wirebox style
var ip = getInstance('ip@ip');

//vanilla style
var ip = new my.lib.ip.models.ip();

This returned value is an object which you can use to retrieve information for the given subetnet.

Below is example along with all the methods available to you:

// instation:
var ip = getInstance('ip@ip');

// you can disable loading all available addresses to speed up performance for large subnets, by default this is true
ip.setLoadRange(false);
ip.setLoadRange(true);

//load subnet
var subnet = ip.v4('192.168.0.1/24');  // or ip.v4('192.168.0.1','255.255.255.0')

// available getters
subnet.getAddress()             // 192.168.0.1
subnet.getNumHosts()            // 254
subnet.getPrefixLength()        // 24
subnet.getBroadcastAddress()    // 192.168.0.255
subnet.getNetworkAddress()      // 192.168.0.0
subnet.getSubnetMask()          // 255.255.255.0
subnet.getCidrSignature()       // 192.168.0.1/24
subnet.getFirstAddress()        // 192.168.0.1
subnet.getLastAddress()         // 192.168.0.254
subnet.getBinary()              // 11000000101010000000000000000001
subnet.getIpDecimal()           // 3232235521
subnet.getNetworkDecimal()      // 3232235520
subnet.getBroadcastDecimal()    // 3232235775
subnet.getAddressses()          // A struct containing all available addresses           

// utility functions
var isInRange = subnet.isInRange('192.168.0.4'); //true
var isInRange = subnet.isInRange('192.168.2.9'); //false

// can return a struct with all the above information of the subnet
var memento = subnet.toMemento();
