Summary

Sergey Olenich

Russian Federation · AI-generated

individual small russia

The AS handle PE_Olenich_AS is held by Sergey Olenich.

What it's used for

  • The address space carries individual or small-scale private usage, indicated by the registrant names Sergey Olenich and Osipenko Alexander Nikolaevich and netnames PE_Sergey_Olenich_Net3 and ORG-OANP1-RIPE.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a small, self-contained network rather than a transit or large access provider.

Notable

  • Registrants for the two announced prefixes are Sergey Olenich and Osipenko Alexander Nikolaevich, both distinct from the AS holder name but consistent with personal or small-team management of the space.
  • The inventory consists of two /24 blocks, 31.40.131.0/24 and 176.96.240.0/24, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, 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 1,783 prefixes, as published 2026-10-17. 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.
