Summary

Petersburg Nuclear Physics Institute

Russian Federation · AI-generated

research government science infrastructure

GRIDPNPI is operated by Petersburg Institute of Nuclear Physics of B.P. Konstantinov.

What it's used for

  • The address space supports the institute's internal computing and research infrastructure, as indicated by the netname KIAE-PNPI and registrant KIAE computing division NOC.
  • The AS announces 2048 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained research network rather than a transit or access provider.

Notable

  • Registrants align with the announcer, listing KIAE computing division NOC and FSBI PNPI, confirming the space belongs to the institute's computing division.
  • The address inventory consists of a single IPv4 block (144.206.128.0/21) and one IPv6 prefix (2001:67c:1bdc::/48), typical for a dedicated institutional network.

Internet exchanges

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Transit providers

2 upstream, 0 downstream and 3 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
