Summary

Sens Bank

Ukraine · AI-generated

banking corporate ukraine

ALFABANK-UA is held by Sens Bank.

What it's used for

  • The space carries corporate banking infrastructure, evidenced by the netname SENSE-BANK-UA and the reverse DNS record alfa-info.com.ua.
  • The AS announces 1024 IPv4 addresses within a single prefix (91.197.216.0/22) and maintains only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal office and data center endpoints for the bank's operations in Kyiv.

Notable

  • Registrant data aligns with the announcer, listing AT SENS BANK for the prefix 91.197.216.0/22.
  • The operator was formerly known as Alfa-Bank Ukraine; it rebranded to Sens Bank following the 2022 invasion to dissociate from the Russian Alfa Bank JSC.
  • The address inventory is a single contiguous /22 block, typical of a corporate estate segmented for internal use.

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.
