Summary

Erste Bank

Croatia · AI-generated

banking corporate croatia

ERSTEBANK is operated by Erste&Steiermarkische Bank d.d.

What it's used for

  • The address space carries corporate banking infrastructure, evidenced by the netname ERSTEBANK and the registrant T-HT Contact.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (195.29.91.0/24) and maintains 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The RDAP registrant T-HT Contact differs from the registry holder Erste&Steiermarkische Bank d.d., suggesting the address space may be managed by a third-party technical contact or reflects post-acquisition administrative structures.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, representing a minimal footprint typical of a specific corporate site or data center segment.

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 1,773 prefixes, as published 2026-10-13. 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.
