Summary
Tower Federal Credit Union
enterprise legacy
TOWERFCU-AS is Tower Federal Credit Union, a Maryland credit union headquartered in Laurel. AS7820 is its corporate network, not a service-provider network.
What it's used for
- Multihomed connectivity for the credit union's own systems: online and mobile banking front ends, branch connectivity and corporate IT.
- The footprint is tiny and entirely self-contained: two adjacent /24s,
204.225.146.0/24and204.225.147.0/24. There is no customer address space and no subscriber-style reverse DNS.
Notable
- This is enterprise address space belonging to a financial institution. A connection from it is a Tower FCU system or an employee behind the corporate network, never a consumer broadband customer.
- A financial institution running its own AS is usually doing it for redundancy and BGP control over its public-facing banking services rather than for any transit role. AS7820 has no downstream networks.
Interesting
- Tower Federal Credit Union was founded in 1953 by seven National Security Agency employees and grew alongside the agency after both moved to Fort Meade; it later separated its identity from its NSA sponsor and today serves a far broader membership. The AS is an ordinary corporate network, with no connection to the agency's own address space.

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 2026-10-13, 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: 440 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.
