A Node.js library providing IP address utilities for parsing, validating, comparing, and converting IPv4 and IPv6 addresses. It supports subnet calculations, CIDR operations, buffer conversions, and private-address detection.

Use cases

• get the machine's local IP address in node.js
• validate whether a string is a valid IPv4 or IPv6 address
• calculate subnet information from a CIDR notation
• convert an IP address to a buffer or long integer and back
• check if an IP address is private
• compare two IP addresses for equality
• compute network and broadcast addresses from an IP and subnet mask

When to choose

• you need lightweight IP address parsing and manipulation in a Node.js project
• you need subnet/CIDR math like network address, broadcast, or range containment checks
• you need to serialize IP addresses into buffers for network protocols

When to avoid

• you need geolocation or public IP lookup - this library does not do network requests
• you are working outside Node.js (e.g., browser or Python)
• you need actively developed features or guaranteed security patches, as the project is in maintenance mode
