Summary

NorthCountry Federal Credit Union

United States of America · AI-generated

business credit-union internal

NCFCU-SB-ASN01 is held by NorthCountry Federal Credit Union.

What it's used for

  • The space carries internal corporate traffic, evidenced by the netname NCFCU-PUBLIC-01 and registrant NorthCountry Federal Credit Union.
  • The AS announces 256 IPv4 addresses across 1 prefix (136.175.253.0/24) with 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal systems for a Vermont-based credit union offering checking, savings, auto loans, and mortgages.

Notable

  • The registrant NorthCountry Federal Credit Union matches the AS holder and netname, confirming consistent ownership.
  • The address inventory is a single /24 block, typical for a small business or branch network requiring a modest public presence.

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 1,782 prefixes, as published 2026-10-16. 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.
