Summary
Bluegrass Network LLC
isp transit legacy
BLUENET is Bluegrass Network LLC, a carrier-owned fibre transport company in Elizabethtown, Kentucky, formed in 1995 by a group of independent Kentucky telephone companies to build a shared fibre ring between them. It is jointly owned by its member telcos.
What it's used for
- Internet access for its members' subscribers. Most of the address space this AS announces — around 20,000 IPv4 addresses across 25 prefixes, plus seven IPv6 prefixes from
2607:f9d0::/32— is registered to Duo Broadband (formerly Duo County Telephone), one of Bluegrass Network's owner-members, and the reverse DNS on it is straightforwardly residential:66-38-64-5.pool.dsl.duo-county.com,66-38-52-5.pool.cbl.duo-county.com. - Those are DSL and cable subscriber pools, so whatever Bluegrass Network is on paper, the space it originates carries ordinary home broadband customers.
- A small amount of the space is registered to Bluegrass Network itself, and its PTRs (
CV-IRING-RTR-01.blue.net) are router infrastructure on the fibre ring.
Notable
- Duo Broadband is a co-owner, not an unrelated registrant, so the mismatch between the ASN holder and the prefix registrants is ownership structure rather than any sign of leased or brokered address space.
- Twenty observed neighbours is more than a pure enterprise and far fewer than a wholesale carrier — consistent with a regional aggregator that hauls its members' traffic to national hubs and peers on their behalf.

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 1,779 prefixes, as published 2026-10-22. 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.
