Summary

Cyber_Folks

Poland · AI-generated

residential isp poland static

The AS handle CF-KRK is operated by Cyber_Folks S.A.

What it's used for

  • The address space carries static residential and business connections, evidenced by reverse DNS entries such as 5E981000.static.tld.pl and netnames like KEI and CF-PL.
  • With 71,936 IPv4 addresses announced across 18 prefixes and only 4 observed neighbours, the high address-to-neighbour ratio indicates an access network providing connectivity to end-users rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are listed as Network Operations Center Cyber_Folks S.A. or Cyber_Folks S.A., while the largest blocks (94.152.0.0/18, 94.152.64.0/18, 94.152.128.0/18) list KEI Administrator as the registrant, reflecting historical ownership or specific block management.
  • The inventory consists primarily of large contiguous blocks in the 94.152.0.0/16 range, supplemented by smaller /22 and /24 allocations from various other ranges.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
