# Network infrastructure
-## VLANs
+## Networks
-NOC runs 2 core switches (one in each room), carrying a bunch of VLANs:
-- 33 is the management VLAN (192.168.33.0/24);
-- 127 is the LAN (192.168.127.0/24);
-- 255 (`0xFF`) is our Funkfeuer VLAN.
+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 IoT network (33);
+- the services interconnect (34) and management (23) networks;
+- the guests (127) and members (128) LANs;
+- the public services network (36, 89.106.211.32/27);
+- the Funkfeuer VLAN (255, `0xFF`).
+
+
+### 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.
-The switches have hostnames `sw{0,1}.mgmt.realraum.at`, and the WiFi access
-points are similarly `ap{0,1}.mgmt.realraum.at`. `0` denotes the main room, and
-`1` denotes Wöhnung 2.
## WiFi
## Physical locations
+The switches have hostnames `sw{0,1}.mgmt.realraum.at`, and the WiFi access
+points are similarly `ap{0,1}.mgmt.realraum.at`. `0` denotes the main room, and
+`1` denotes Wöhnung 2.
