Description

Production mediawiki uses this:

$wgHTCPRouting = [
        '' => [
                'host' => '239.128.0.112',
                'port' => 4827
        ]
];

Wikitech is behind misc-web, so that will purge the wrong varnishes when a page on wikitech changes. Is there an equivalent multicast IP for the misc-web varnishes?
