11 years ago That tag actually already exists. It just got left out of the documentation somehow. You can use any of the return values from http://php.net/manual/en/function.parse-url.php in that tag pair.
It'll be nice to only show the host part of the url (e.g.: http://www.google.de -> www.google.de). I'd suggest
{field_name}{host}{/field_name}
