About this network

The network of the City of Vienna's municipal administration, registered to Magistratsabteilung 01 — Wien Digital, the city's central IT department. The handle is MAGWIEN.

What it's used for

• Carrying the city administration's own IT: municipal departments and offices, city-run hospitals and nursing homes, schools, and the digital services residents use to deal with the city.
• Wien Digital runs the city's own data centre and operates well over a thousand services from it, so this AS is both an office network and a service-hosting network for the municipality.

Notable

• Government address space, not a public ISP. Addresses here belong to a city government's staff, facilities and applications; they are not sold to anyone.
• The AS announces a full legacy /16 (141.203.0.0/16) — a large, tidy allocation of the kind that large public institutions picked up early and have simply kept.

Interesting

• Wien Digital was formed by merging the IT departments of the city administration, the Vienna hospital association and the AKH university hospital into one unit, which is why a single municipal AS ends up spanning both civic administration and healthcare.
