Summary

Avalon

Croatia · AI-generated

hosting content croatia

AVALON-AS is operated by cyber_Folks d.o.o.

What it's used for

  • The space carries content delivery infrastructure, as indicated by the PeeringDB classification of "Content" and the reverse DNS pattern as201563.net.
  • The network announces 1024 IPv4 addresses across 1 prefix (185.58.72.0/22) and maintains 4 observed neighbours, a ratio consistent with a hosting or content provider rather than a transit carrier.
  • Traffic from this AS consists of web and API endpoints serving content to European users, aligned with the operator's "Content" peering scope.

Notable

  • The registrant cyber_Folks d.o.o matches the AS holder, with the netname HR-AVALON-20140520 confirming the association.
  • The address inventory is a single contiguous /22 block, indicating a compact and unified allocation.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
