# Is ip-address ESM-only? Can you require() it?

A library for parsing IPv4 and IPv6 IP addresses in node and the browser.

Last verified Sep 9, 2026 against ip-address@10.7.0.

ip-address ships CommonJS only. require("ip-address") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 12. import "ip-address" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("ip-address") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 12.
2. From ES modules use the default import: import ipAddress from "ip-address"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
