+### Conventions
+
+We use a number of conventions to make things more consistent:
+
+- The DNS zone for a given network is `NET.realraum.at`, with the exception
+  of the public services network (which has `realraum.at`);
+- Networks using RFC 1918 IP space use the 192.168.VID.0/24 subnet;
+- The gateway for a network is on the last IP for the subnet.
