 NOC operates a number of networks, available as tagged VLANs on the core
 switches (one in each half of the hackerspace).  These networks are:

 - The DNS zone for a given network is `NET.realraum.at`, with the exception
   of `pub` (which uses `realraum.at`) and of the Funkfeuer VLAN (which has no
   `realraum.at` zone).
-- Networks using RFC 1918 IP space use the 192.168.VID.0/24 subnet;
+- When a network uses RFC 1918 IP space, it is the 192.168.VID.0/24 subnet;
   for instance, the `iot` network has id 33 and uses the 192.168.33.0/24 subnet.
 - The gateway for a network is on the last IP for the subnet.
