Unclassified ARIN
Summary
Keldysh Institute of Applied Mathematics
research government math hpc
ASN-KIAM is operated by Keldysh Institute of Applied Mathematics, a research institute within the Russian Academy of Sciences.
What it's used for
- The space carries internal research and high-performance computing traffic, as indicated by the registrant netname
RU-KIAM-20021028and the institute's focus on computational mathematics. - The AS announces a single IPv4 prefix,
217.9.80.0/22, comprising 1024 addresses, and maintains 11 observed neighbours, a ratio consistent with a dedicated institutional network rather than a transit provider.
Notable
- The RDAP registrant matches the AS holder exactly, confirming the address space is owned and operated by the Keldysh Institute of Applied Mathematics.
- The address inventory consists of a single contiguous /22 block, reflecting a compact and self-contained corporate estate typical of a scientific research facility.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
