Summary
Blackfoot Telephone Cooperative
telecom isp business
The netname carries the AS number, and the reverse names mix two separators.
What it's used for
- A telephone cooperative's network. A single IPv4
/23and one IPv6/40announced from the United States, through one observed BGP neighbour.
Notable
- The netname is the cooperative's name, this AS number written out in full, and the block's first address, so the label ties the allocation to the routing identifier.
- The AS handle is three initials and the word lab, which names a purpose rather than the organisation.
- Both answering addresses write the first two octets with dots and join the last two with a hyphen, under a domain belonging to none of the parties on record.
- Three addresses were queried for reverse DNS and two returned a name.
- The IPv6 allocation is large where the IPv4 block is small.
Interesting
- Mixing dots and a hyphen inside one address is the strangest separator choice in this range. Each half is a sensible convention; together they mean no single rule parses the name.
- A handle naming a lab suggests this number was registered for testing and kept in service, which is a common way small operators end up with more AS numbers than they planned.
- A fourth domain answering for the cooperative's addresses points at a shared operations arrangement between small carriers, the same pattern seen elsewhere in this range.

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 1,772 prefixes, as published 2026-10-15. 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.
