Summary

VSK Insurance Joint Stock Company

Russian Federation · AI-generated

insurance corporate russia

VSK is operated by VSK Insurance Joint Stock Company.

What it's used for

  • The address space carries corporate infrastructure for a Russian insurance company, as indicated by the registrant "VSK Insurance Joint Stock Company" and netnames RU-VSK-20200609 and VSK-NET.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 3 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal business endpoints for VSK, a major Russian insurer providing services to the energy sector and other entities.

Notable

  • Registrants for both announced prefixes (94.124.114.0/24 and 193.8.0.0/24) are listed as "VSK Insurance Joint Stock Company", agreeing with the AS holder.
  • The address inventory is finely subdivided into two /24 blocks, typical of site-by-site segmentation for a corporate 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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
