Location: hostname property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The hostname property of the Location interface is a string containing either the domain name or IP address of the location URL. If the URL does not have a hostname, this property contains an empty string, "". IPv4 and IPv6 addresses are normalized, such as stripping leading zeros, and domain names are converted to IDN.

See URL.hostname for more information.

Value

A string.

Examples

js
console.log(window.location.hostname);
// developer.mozilla.org

const anchor = document.createElement("a");
anchor.href = "https://developer.mozilla.org:4097/";
console.log(anchor.hostname === "developer.mozilla.org");
// The port number is not included in hostname
