Summary
BluegrassNet (Intermart)
isp legacy
Autonomous System 4261 (BLUEGRASSNET) belongs to Intermart Inc., trading as BluegrassNet, a regional internet service provider in Louisville, Kentucky.
What it's used for
- Business internet access, fiber, and wireless WAN connectivity for commercial customers across the Louisville area.
- Hosting and colocation services out of the provider's own facility.
Notable
- Business-facing rather than eyeball address space. BluegrassNet positions itself around commercial customers, so an IP here is more likely an office or a hosted server than a home.
- Founded in 1994, it is one of the independent regional ISPs from the first commercial wave of the internet, and its AS number and address space date from that period.

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 1,781 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.
