Since you seem to want to allow local IP addresses only, I wonder why your wiki is even reachable from anywhere else.
In specific cases, the wiki is used by different groups of children. Who use this in places of their lifestyle. These can be configured meaningfully.
It can therefore do no harm to configure it in such a way that any uninvited external guests, despite existing deliberate or unintentional misconfigurations, do not make the children's data freely available on the Internet or in local networks.
Locking out public networks would represent a certain intrinsic safety of the wikis that are portable in the specific case on local computers or in LANs.
Its looks like for access by localhost no need IP range can banned by:
* IPv6 ::0 and ::2/0 , that shold bann all IPv6 IPs than the IPv6 localhost IP ::1
* How to ban the full range of no need IPv4 IPs than 127.0.0.1 are not clear on this time
