Location: hostname property

{{ApiRef("URL API")}}

The hostname property of the {{domxref("Location")}} interface is a string containing either the {{glossary("domain name")}} or {{glossary("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 {{domxref("URL.hostname")}} for more information.
