Summary
Irkutsk Scientific Centre (SB RAS)
education research legacy
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
84.237.16.0/20carrying 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.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,854 prefixes, as published 2026-11-06. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
