Hi,
I cannot find a piece of information about $subject.
As help page <https://www.mediawiki.org/wiki/Help:Range_blocks/IPv6> was
moved from Meta to MediaWiki, it gives now a general talk instead of actual
information. It says: "Like IPv4, IPv6 rangeblocks are limited by
$wgBlockCIDRLimit <https://www.mediawiki.org/wiki/Manual:$wgBlockCIDRLimit>,
which by default allows rangeblocks of up to /64 in size (before MediaWiki
1.20wmf5, which changes the default to /19)."
All right, but what is the actual value for WMF wikis, and where is this
information available?
