Summary

Transstroibank

Russian Federation · AI-generated

bank business corporate

The AS handle TSB-AS is held by JSC "Transstroibank".

What it's used for

  • The address space carries corporate infrastructure for a Russian commercial bank, as indicated by the netname TRANSSTROYB and registrant JSC "Transstroibank".
  • The network announces a single IPv4 prefix (193.42.145.0/24) comprising 256 addresses with 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal banking systems for Transstroibank, a non-public joint stock company based in Moscow.

Notable

  • The RDAP registrant JSC "Transstroibank" matches the AS holder, confirming the space is owned and operated by the bank itself.
  • The inventory is minimal, consisting of one /24 block with no IPv6 prefixes, reflecting a small-scale internal network footprint.

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 1,772 prefixes, as published 2026-10-15. 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.
