+### `svc` -- Services LAN
+
+This network is intended for services that aren't directly exposed to users
+(be they humans or machines); this includes services exposed through a frontend
+(like realraum web services) and services only meant to be consumed by another
+service (like a database server).
+
+
+### `pub` -- Publicly-available services
+
+This network is intended for services that can be consumed by non-NOC systems,
+including our HTTP(S) frontend -- `entrance`, `mqtt`, ...
+
+Services in this network can restrict availability, for instance by only
+allowing clients connecting from our LANs, or by requiring authentication.
+
+No RFC 1918 subnet is used on this network, only `89.106.211.64/27`.
