Summary
Blackfoot Communications
telecom rural cooperative residential
BCI is the autonomous system for Blackfoot Communications, a rural telecommunications cooperative in Western Montana.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
static.blackfoot.net,cutcom.net, andcentric.net. - With 70,144 IPv4 addresses announced across 29 prefixes and 30 observed neighbours, the ratio indicates an access network serving local subscribers rather than a transit provider.
Notable
- All sampled registrants are listed as Blackfoot Telephone Cooperative, Inc., matching the AS holder and confirming consistent ownership of the inventory.
- The inventory includes netnames like
MONTANA-COMandFREMONT, reflecting historical acquisitions or regional service areas within the cooperative's footprint. - The address inventory is finely subdivided into multiple /19, /20, and /21 blocks, typical of a regional ISP managing distinct customer segments or legacy allocations.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
