Summary

Ljubljana Stock Exchange

Slovenia · AI-generated

business financial exchange slovenia

LJSE-AS is operated by Ljubljanska borza d.d., the Ljubljana Stock Exchange.

What it's used for

  • The space carries the internal network of the stock exchange, identified by the netname LJSE and registrant LJUBLJANSKA BORZA d.d. Ljubljana.
  • The AS announces a single IPv4 prefix of 256 addresses (193.109.227.0/24) with 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.

Notable

  • The registrant LJUBLJANSKA BORZA d.d. Ljubljana matches the AS holder, confirming direct ownership of the address space.
  • The Ljubljana Stock Exchange was purchased by the Vienna Stock Exchange in 2008 and later by the Zagreb Stock Exchange.
  • The inventory consists of a single /24 block with no IPv6 prefixes, typical for a specialized institutional 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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
