Summary

K2 Cloud

Russian Federation · AI-generated

cloud hosting enterprise russia

The AS handle K2_INT is held by K2 Integration JSC, operating as K2 Cloud.

What it's used for

  • The address space carries cloud infrastructure, evidenced by reverse DNS entries such as c2-5-35-74-0.elastic.k2.cloud and c2-91-184-234-0.elastic.k2.cloud.
  • The network announces 18,176 IPv4 addresses across 22 prefixes and 1 IPv6 prefix, with 35 observed neighbours, indicating a hosting or cloud provider role rather than a transit or access network.
  • Traffic from this AS consists of cloud service endpoints and elastic compute resources for K2 Cloud's customers.

Notable

  • Registrants for the majority of prefixes are "Network Operation Centre; K2 Integration JSC; Abuse-C Role", consistent with the announcer.
  • Two prefixes (5.8.180.0/23 and 81.23.10.0/23) list "CROC DC operations group; MegaFon PJSC - Internet Service Network Operation Center" as registrants, suggesting leased or historically allocated space.
  • One prefix (93.189.226.0/23) is registered to "Mikhail Tonkonog" under netname RU-IPMAGNAT-20120810, which does not align with the primary K2 Integration registrant.
  • The inventory is finely subdivided into /21, /22, /23, and /24 blocks, typical of an internal corporate or cloud estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
