I really think it&#x27;s time for guides to be written that don&#x27;t contain the advice to disable all IPv6 support. IPv6 is coming. It&#x27;s 2015 and categorically disabling (or actually just breaking) IPv6 definitely isn&#x27;t good advice any more.<p>Yes. The article did qualify that advice with &quot;unless you&#x27;re using it...&quot;, but people should be doing v6, so advice should include v6 too.
