A comprehensive TypeScript package for IP address manipulation and subnet calculations.
Table of Contents
Description
ip-navigator is a powerful and user-friendly TypeScript package designed to simplify IP address management and subnet calculations. Whether you're a network administrator, developer, or student learning about networking, this tool provides an intuitive set of functions for handling various IP address operations.
Features
- Validate IPv4 addresses and subnet masks
- Convert between decimal, binary, and integer IP formats
- Perform subnet calculations (network address, broadcast address, available hosts)
- Manipulate and compare IP addresses
- Work with CIDR notation
- Classify IP addresses (public, private)
- Generate IP address ranges
- Check if IP addresses belong to specific subnets
- Full TypeScript support with type definitions
- Comprehensive test suite using Jest
Installation
To install ip-navigator, run the following command in your terminal:
npm install ip-navigator
pnpm add ip-navigator
Usage
ip-navigator is designed for use in TypeScript projects. Here's a basic example of how to use it:
import { isValidIPAddress, ipToBinary } from "ip-navigator";
// Example usage
console.log(isValidIPAddress("192.168.1.1")); // true
console.log(ipToBinary("192.168.1.1")); // '11000000.10101000.00000001.00000001'
API Reference
Validation Functions
isValidIPAddress(ipAddress: string): boolean
Validates whether the given string is a valid IPv4 address.
isValidIPAddress("192.168.1.1"); // returns true
isValidIPAddress("256.1.2.3"); // returns false
isValidSubnetMask(subnetMask: string): boolean
Checks if the given string is a valid subnet mask.
isValidSubnetMask("255.255.255.0"); // returns true
isValidSubnetMask("255.255.256.0"); // returns false
isValidCIDR(cidr: string): boolean
Checks if the given string is a valid CIDR notation.
isValidCIDR("192.168.1.0/24"); // returns true
isValidCIDR("192.168.1.0/33"); // returns false
Conversion Functions
ipToBinary(ipAddress: string): string
Converts an IPv4 address to its binary representation.
ipToBinary("192.168.1.1"); // returns '11000000.10101000.00000001.00000001'
binaryToIP(binaryIP: string): string
Converts a binary representation of an IP address to its decimal format.
binaryToIP("11000000.10101000.00000001.00000001"); // returns '192.168.1.1'
ipToInteger(ipAddress: string): number
Converts an IPv4 address to its integer representation.
ipToInteger("192.168.1.1"); // returns 3232235777
integerToIP(integer: number): string
Converts an integer representation of an IP address to its decimal format.
integerToIP(3232235777); // returns '192.168.1.1'
Subnet Operations
calculateNetworkAddress(ipAddress: string, subnetMask: string): string
Calculates the network address based on an IP address and subnet mask.
calculateNetworkAddress("192.168.1.100", "255.255.255.0"); // returns '192.168.1.0'
calculateBroadcastAddress(ipAddress: string, subnetMask: string): string
Calculates the broadcast address based on an IP address and subnet mask.
calculateBroadcastAddress("192.168.1.100", "255.255.255.0"); // returns '192.168.1.255'
getSubnetInfo(ipAddress: string, subnetMask: string): SubnetInfo
Retrieves comprehensive information about a subnet.
getSubnetInfo("192.168.1.100", "255.255.255.0");
// returns {
// networkAddress: '192.168.1.0',
// broadcastAddress: '192.168.1.255',
// totalHosts: 256,
// usableHosts: 254,
// firstUsableHost: '192.168.1.1',
// lastUsableHost: '192.168.1.254'
// }
IP Address Operations
getNextIPAddress(ipAddress: string): string
Returns the next IP address in sequential order.
getNextIPAddress("192.168.1.1"); // returns '192.168.1.2'
getPreviousIPAddress(ipAddress: string): string
Returns the previous IP address in sequential order.
getPreviousIPAddress("192.168.1.2"); // returns '192.168.1.1'
isIPAddressInSubnet(ipAddress: string, networkAddress: string, subnetMask: string): boolean
Checks if an IP address belongs to a given subnet.
isIPAddressInSubnet("192.168.1.100", "192.168.1.0", "255.255.255.0"); // returns true
isPublicIP(ipAddress: string): boolean
Checks if an IP address is a public IP address.
isPublicIP("8.8.8.8"); // returns true
isPublicIP("192.168.1.1"); // returns false
isPrivateIP(ipAddress: string): boolean
Checks if an IP address is a private IP address.
isPrivateIP("192.168.1.1"); // returns true
isPrivateIP("8.8.8.8"); // returns false
getIPRange(startIP: string, endIP: string): string[]
Generates an array of IP addresses within the specified range.
getIPRange("192.168.1.1", "192.168.1.3");
// returns ['192.168.1.1', '192.168.1.2', '192.168.1.3']
