subnet-cidr-adviser

=================

JavaScript class for calculating all possible subnets, subnet validity, ip range

What does it do?
----------------

* Calculates all possible subnets within the given vpc.

* Calculates IP range available within each of the subnet.

* Calculates if subnet you are trying to create is already taken or overlapping with existing subnet (you need to provide a list of existing subnets).

* Suggest next possible subnet (you need to provide a list of existing subnets).

* Takes a Subnet CIDR network address and returns information ( all hosts, start address, end address)

Node.js
-------

`javascript
var SubnetCIDRAdviser = require( 'subnet-cidr-calculator' );

var existingSubnetCIDR = ['10.0.32.0/19'];
var probabal_subnets = SubnetCIDRAdviser.calculate('10.0.0.0' , '16', existingSubnetCIDR);
var is_overlap = SubnetCIDRAdviser.isSubnetOverlap(existingSubnetCIDR, '10.0.32.0/20');
console.log(is_overlap, 'subnetOverlap');
var ip_range = SubnetCIDRAdviser.getIpRangeForSubnet( '10.0.32.0/20' );
console.log('IP range for 10.0.32.0/20 is', ip_range);

var subnetdetails = SubnetCIDRAdviser.getSubnetDetails( '10.0.32.0/20' );
console.log('Details for 10.0.32.0/20 is', subnetdetails);

var parentVPC_CIDR = '10.0.0.0/16';
var cidrToValidate = '';
var getNextValidCIDR = SubnetCIDRAdviser.getNextValidCIDR( parentVPC_CIDR, existingSubnetCIDR, probabal_subnets, cidrToValidate );
console.log('getNextValidCIDR is', getNextValidCIDR);
`


RequireJS
---------

`javascript
require( [ 'ip-subnet-calculator' ],

function( SubnetCIDRAdviser )
{
console.log( SubnetCIDRAdviser.calculate( '10.0.0.0', '16', existingSubnetCIDR ) );
} );
