Croatia · AI-generated

airport business infrastructure

What it's used for

  • The space carries the internal network of Split Airport, identified by the netname ZLSPLIT-HR and registrant Zracna luka Split d.o.o.
  • The inventory consists of a single IPv4 prefix, 193.242.141.0/24, comprising 256 addresses, with 0 IPv6 prefixes announced
  • With 2 observed neighbours, the low address-to-neighbour ratio indicates a small, self-contained site network rather than a transit or access provider
  • Traffic from this AS consists of internal airport systems, office workers, and support activities for air transportation

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
