Summary

Digital Federal Credit Union

United States of America · AI-generated

business financial credit-union

DCU-LCO1 is the autonomous system for Digital Federal Credit Union.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname DFCU-19 associated with both announced prefixes.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small-scale business network with limited peering.

Notable

  • The registrant for both prefixes is Digital Federal Credit Union, which aligns perfectly with the AS holder.
  • The inventory consists of two /24 blocks, 174.34.230.0/24 and 204.144.135.0/24, representing a modest internal estate for a financial institution.

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: 454 networks and 1,854 prefixes, as published 2026-11-09. 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.
