AS8506 Academy of Irkutsk Scientific Centre of Siberian Department of RAN

AS8506 is the academic network of the **Irkutsk Scientific Centre of the Siberian

Branch of the Russian Academy of Sciences**. The AS is registered to the Matrosov

Institute for System Dynamics and Control Theory (ISDCT SB RAS), which runs the

Irkutsk Supercomputer Centre and acts as the network operator for the city's

academic campus.

What it's used for

• A single 84.237.16.0/20 carrying the research institutes clustered in Irkutsk's academic district, plus the supercomputer centre's own services.
• Institutional connectivity for laboratories, mail and web servers, and scientific instrumentation.

Notable

• rDNS reads as a directory of the Scientific Centre's constituent institutes: icc.ru (the supercomputer centre and its routers), iszf.irk.ru (Institute of Solar-Terrestrial Physics — including hosts named after telescopes), igc.irk.ru (Institute of Geochemistry), irigs.irk.ru. There is no subscriber, DSL or dynamic-pool naming anywhere in the block.
• The AS is single-homed with one observed neighbour, the normal shape for a regional academic site that reaches the internet through one upstream rather than peering broadly.

Interesting

• The presence of solar-physics observatory hosts reflects Irkutsk's role in Russian heliophysics: ISTP SB RAS operates radar and telescope facilities across the Baikal region, and their data flows out through this address space.
