This doesn&rsquo;t handle IPv6 addresses correctly &mdash; <code>u.hostname</code> includes brackets for IPv6 but <code>toLowerCase()</code> is still safe there. The real issue is <code>URL</code> constructor will throw on <code>raw</code> values that aren&rsquo;t absolute URLs. Should add a try/catch or require callers to pre-validate.
