Summary

JSC UCB

Russian Federation · AI-generated

business russia corporate

The AS handle OKB-AS is held by JSC UCB.

What it's used for

  • The address space carries corporate infrastructure, with netnames ORG-CO27-RIPE and JSC-UCB registered to JSC UCB, and HK-NEXT-20220425 registered to Next Limited.
  • The network announces 1280 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a small, isolated corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for JSC UCB, a Russian joint-stock company.

Notable

  • Registrants for two of the three prefixes are JSC UCB, while the 185.145.54.0/23 prefix is registered to Next Limited, suggesting leased or acquired address space.
  • The inventory is small and fragmented, consisting of two /23 blocks and one /24 block, typical of a single organization's internal network.

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: 455 networks and 1,849 prefixes, as published 2026-11-14. 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.
