Summary
Hopkinsville Electric System
isp telecom infrastructure
An electric utility selling internet access, with reverse names built two structurally different ways.
What it's used for
- A municipal electric utility running a broadband network. 24,320 addresses across 18 IPv4 prefixes, the IPv6 block
2606:6dc0::/32, and nine observed BGP neighbours.
Notable
- Most addresses answer as
255-231-64-38.hesenergy.net, all four octets reversed into one label. - Addresses in one block answer as
255-219.8.8.hesenergy.netinstead, with a two-octet label sitting under a subzone that keeps the other two octets in forward order. - Blocks come from three different carriers as well as the utility itself.
66.255.240.0/21is netname66-255-240-0-20and50.30.116.0/22is50-30-112-0-20, both naming a larger parent than the block they cover.- Netname
CENTURYLINK-LEGACY-QWEST-INET-8appears again here, with a different counter.
Interesting
- The two reverse schemes are not a formatting difference but a structural one. One puts the whole address in a single label; the other delegates a subzone per parent block and names only what is left. Both live in the same domain, under one operator, at the same time.
- A utility whose domain name says energy, selling connectivity over its own poles, is the municipal broadband model. The address space came from whoever would sell it, which is why four sources appear.
- Netnames naming the parent rather than the assignment recur across this range, and always make the registry claim a wider delegation than exists.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,771 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.
