HTMLAnchorElement: hostname property

The hostname property of the HTMLAnchorElement interface is a string containing either the domain name or IP address of the <a> element’s href. 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 hostname for more information.

Value
