		Milliseconds to wait for a server to respond.

		Internet Protocol version to use. This is an advanced option that is usually not necessary to be set, but it can prove useful to specifically assert IPv6 connectivity.

The following checks are run in parallel:

- Retrieve [icanhazip.com](https://github.com/major/icanhaz) via HTTPS

- Query `myip.opendns.com` on OpenDNS (Node.js only)

- Retrieve Apple's Captive Portal test page (Node.js only)

When the first check succeeds, the returned Promise is resolved to `true`.

When any check succeeds, the returned Promise is resolved to `true`.

# is-online [![Build Status](https://travis-ci.com/sindresorhus/is-online.svg?branch=master)](https://travis-ci.com/github/sindresorhus/is-online)

Works in Node.js and the browser *(with a bundler)*.

In the browser you have [`navigator.onLine`](https://developer.mozilla.org/en-US/docs/Web/API/NavigatorOnLine.onLine), but it's useless as it only tells you if there's a local connection, and not whether the internet is accessible.

Milliseconds to wait for a server to respond.

Internet Protocol version to use. This is an advanced option that is usually not necessary to be set, but it can prove useful to specifically assert IPv6 connectivity.

- Retrieve [icanhazip.com](https://github.com/major/icanhaz) (or [ipify.org](https://www.ipify.org) as fallback) via HTTPS.

- Query `myip.opendns.com` and `o-o.myaddr.l.google.com` DNS entries. *(Node.js only)*

- Retrieve Apple's Captive Portal test page (this is what iOS does). *(Node.js only)*

To make it work through proxies, you need to set up [`global-agent`](https://github.com/gajus/global-agent).
