public-ip

Get your public IP address - very fast!

In Node.js, it queries the DNS records of OpenDNS, Google DNS, and HTTPS services to determine your IP address. In browsers, it uses the excellent icanhaz and ipify services through HTTPS.

Install

npm install public-ip

Usage

import {publicIp, publicIpv4, publicIpv6} from 'public-ip';

console.log(await publicIp()); // Falls back to IPv4
//=> 'fe80::200:f8ff:fe21:67cf'

console.log(await publicIpv6());
//=> 'fe80::200:f8ff:fe21:67cf'

console.log(await publicIpv4());
//=> '46.5.21.123'

API

publicIp(options?)

A .cancel() method is available on the promise, which can be used to cancel the request.

publicIpv4(options?)

A .cancel() method is available on the promise, which can be used to cancel the request.

options

Type: object

onlyHttps

Type: boolean
Default: false

Use a HTTPS check using the icanhazip.com service instead of the DNS query. ipify.org is used as a fallback if icanhazip.com fails. This check is much more secure and tamper-proof, but also a lot slower. This option is only available in the Node.js version. The default behaviour is to check against DNS before using HTTPS fallback. If set to true, it will only check against HTTPS.

fallbackUrls

Type: string[]
Default: []

Add your own custom HTTPS endpoints to get the public IP from. They will only be used if everything else fails. Any service used as fallback must return the IP as a plain string.

import {publicIpv6} from 'public-ip';

await publicIpv6({
	fallbackUrls: [
		'https://ifconfig.co/ip'
	]
});

timeout

Type: number
Default: 5000

The time in milliseconds until a request is considered timed out.

IpNotFoundError

Error thrown when the public IP address could not be found.

CancelError

Error thrown when the operation was canceled.
