Summary

OTP Banka Srbija

Serbia · AI-generated

bank business corporate

OTP-BANKA-SRBIJA is operated by OTP Banka Srbija.

What it's used for

  • The address space carries corporate banking infrastructure, identified by the netname OTP-BANKA and registrant OTP Banka Srbija.
  • The AS announces 512 IPv4 addresses within a single prefix (91.232.236.0/23) and maintains 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate systems, branch backhaul, and web/API endpoints for the bank's operations in Serbia.

Notable

  • The RDAP registrant OTP Banka Srbija matches the AS holder and netname OTP-BANKA, confirming consistent ownership.
  • The operator was formerly known as Vojvođanska Banka, which was acquired by OTP Bank in 2017 and rebranded as OTP Banka Srbija in 2021.
  • The inventory consists of a single contiguous /23 block, typical of a corporate estate segmented for internal use.

Reputation

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
