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]

Installation

Node.js

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

require[ [ 'ip-subnet-calculator' ],

function[ SubnetCIDRAdviser ]
{
   console.log[ SubnetCIDRAdviser.calculate[ '10.0.0.0', '16', existingSubnetCIDR ] ]; 
} ];
