Unclassified APNIC
Summary
Peak Credit Union
enterprise legacy
TSCU-01 belongs to Peak Credit Union, a member-owned financial institution serving Washington and Oregon. The handle is the giveaway to its history: TSCU is TwinStar Credit Union, the Olympia, Washington credit union that merged with Northwest Community Credit Union and adopted the unified Peak brand in 2025. This is a single-institution enterprise AS, not a service provider.
What it's used for
The internet edge of a mid-size credit union. RIS observes one IPv4 prefix, 24.104.61.0/24, carrying 256 addresses, no IPv6, and two observed neighbours. Two neighbours is the classic shape of an organisation multihoming for resilience: it buys transit from a couple of providers so that a single carrier outage does not take online banking offline. It sells transit to nobody, and 256 addresses is far too little space for anything else.
A regulated financial institution runs an AS for exactly this reason. Portable address space means the public-facing services — online and mobile banking front ends, VPN termination for branches and remote staff, secure file transfer to core processors and payment networks — keep the same IP addresses through a change of carrier. Firewall rules and partner allowlists at the other end do not have to be renegotiated. Branch connectivity itself rides private circuits, not this block.
Notable
The /24 is registered to TWINSTAR-CREDIT-UNION, org TwinStar Credit Union, while the AS holder is now Peak Credit Union. That is a registrant that has not caught up with a rebrand, not a third party: same institution, two names, one before the merger and one after. The gap is corporate history, not a leasing signal.
Interesting
Peak now serves more than 250,000 members across two states with roughly $4 billion in assets, all of it reached through this one /24. The size of a financial institution says almost nothing about the size of its routed footprint.

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 2026-11-05, 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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
