Summary

P1FCU

United States · AI-generated

finance business enterprise

The same counter is padded to two digits on the AS and left at one on the block.

What it's used for

  • A credit union's network. 256 addresses in the single IPv4 prefix 142.202.64.0/24, two observed BGP neighbours, and no IPv6 announced.

Notable

  • The AS handle is P1FCU-01 and the block is netname P1FCU-1, the same name with the counter written two ways.
  • The registrant is the same string again, with nothing spelled out.
  • The organisation's name carries a digit in its second position, which most registry conventions would have to work around.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • Zero-padding one counter and not the other is a difference nobody would notice until they tried to match the two records automatically. Both objects belong to the same organisation, were created in the same registry, and still disagree about how to write the number one.
  • A credit union announcing a single /24 with two upstreams is buying the ability to keep its own addresses when it changes carrier. For a member-facing institution that is worth more than the address count suggests.
  • Nothing here is spelled out anywhere: an initialism in the handle, the netname and the registrant, with no long form in any field. A reader who does not already know the organisation learns nothing about it from the records.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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 1,783 prefixes, as published 2026-10-20. 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.
