Summary

CloudFerro

Poland · AI-generated

cloud hosting business

The AS handle CF_CLOUD_EXT is held by CloudFerro S.A.

What it's used for

  • The address space carries cloud infrastructure, as indicated by the netname PL-CLOUDFERRO-20191111 and the registrant CLOUDFERRO ADMIN.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small-scale hosting or cloud provider rather than a transit or large access network.
  • Traffic from this AS consists of cloud service endpoints and hosted workloads, reflecting CloudFerro's business as a cloud infrastructure provider.

Notable

  • Registrants for both announced prefixes (91.234.10.0/24 and 91.234.20.0/24) are CLOUDFERRO ADMIN; CloudFerro S.A; Abuse-C Role, which aligns with the AS holder.
  • The address inventory is compact, consisting of two /24 blocks in Poland, with no IPv6 prefixes in the inventory.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
