KNOWNHOLDINGS-AS is operated by Fatcat Network S.A.

What it's used for

  • The address space carries a single IPv4 block, 45.87.220.0/22, registered under the netname BZ-FATCAT-20190617 with registrants FATCAT Administrator, FATCAT NETWORK S.A., and FATCAT Legal Person.
  • The AS announces 1024 IPv4 addresses across 1 prefix and maintains 3 observed routing neighbours, a ratio consistent with a small-scale business or internal corporate estate rather than a large access or transit provider.

Notable

  • The RDAP registrants align directly with the AS holder, identifying FATCAT NETWORK S.A. as the consistent entity across registry records.
  • The address inventory consists of a single contiguous /22 block located in Belize, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
