A TypeScript library for network utilities.
You can install net-utils-lib
using npm:
npm install net-utils-lib
Or with yarn:
yarn add net-utils-lib
Here's a basic example of how to use the utilities provided by this package:
import {isValidIPv4} from 'net-utils-lib';
// Check if an IP address is valid
const isValid = isValidIPv4('192.168.1.1');
console.log(`Is valid IP: ${isValid}`);
// Calculate the network address
const networkAddress = calculateNetworkAddress('192.168.1.10', '255.255.255.0');
console.log(`Network Address: ${networkAddress}`);
// Calculate available IPs in a subnet
const availableIPs = calculateAvailableIPs('24');
console.log(`Available IPs: ${availableIPs}`);
Checks if the provided IP address is a valid IPv4 address.
Checks if the provided CIDR notation is valid.
Returns the class of the provided IP address.
Converts an IP address to its binary representation.
Converts a binary string to an IP address.
Calculates the subnet mask for a given CIDR notation.
Calculates the CIDR notation from a given subnet mask.
Normalizes a subnet mask or CIDR notation to CIDR.
Calculates the network address for a given IP and subnet mask or CIDR.
Calculates the wild card mask for a given subnet mask or CIDR.
Calculates the broadcast address for a given IP and subnet mask or CIDR.
calculateIPRange(networkAddress: string, subnetMaskOrCIDR: string): { firstIP: string; lastIP: string }
Calculates the IP range for a given network address and subnet mask or CIDR.
Calculates the number of available IPs in a subnet.
Calculates the required subnets for given host counts.
allocateSubnets(ip: string, subnetMaskOrCIDR: string, hostsPerSubnet: number[]): { network: string; subnetMask: string; cidr: number; broadcast: string; firstIP: string; lastIP: string; availableIPs: number }[]
Allocates subnets from a given IP address and subnet mask or CIDR.
