Summary
Central 1 Credit Union
finance business enterprise
The only block that answers in reverse is the one belonging to somebody else.
What it's used for
- A credit union's network. Five IPv4 prefixes and one IPv6 prefix announced from Canada, with three observed BGP neighbours.
Notable
- Three fields spell the holder three ways: the AS handle runs the words together, one netname is the acronym
CUCBC, and another writes the whole name out asCENTRAL-1-CREDIT-UNION. - One announced block is registered to a carrier under the netname
BNFD, and it is the only block whose addresses returned reverse names, all under that carrier's domain. - The other blocks carry a hostmaster contact concatenated into the registrant field with a semicolon.
- Fifteen addresses were queried and three returned a name, all from the carrier's block.
Interesting
- The sampling result is the useful part. A financial network publishes nothing about its own addresses and the carrier publishes address-derived names for the space it leases out, so the only visible names on this AS number describe the supplier rather than the customer.
- An acronym netname on the oldest-looking blocks and the full name on another is the ordinary archaeology of a record maintained over decades by different people. Neither is wrong; nothing reconciles them.
- Three upstreams for fifteen hundred addresses is a lot of transit for the space, which is what a network buys when reachability matters more than volume.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
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.
