Summary
Buckeye Cablevision
isp telecom media
Every address sampled answered, including the .0 and .255 of each block.
What it's used for
- A cable television and internet provider. 231,680 addresses across 118 IPv4 prefixes, the IPv6 block
2600:2800::/30, and twenty-eight observed BGP neighbours.
Notable
- Most blocks are netname
BUCKEYE-CABLESYSTEM, several with a contact calledDNS-TECH. - Two blocks in
134.228carry a netname that reads like somebody's surname. - All eighteen sampled addresses answered, every one as
cm-followed by the address, underbuckeyecom.net. - Two prefixes failed their registry lookup, so nothing is known about them here.
Interesting
cmis cable modem. The provider generates a name for every address in every block, so the reverse zone is complete by construction rather than by anyone maintaining it. That is why72.240.208.0and72.241.159.255both answer: a script does not know those two are special.- A surname where a netname should be is a record created by whoever requested the block, back when the person and the organisation were interchangeable in the paperwork. It survives because nobody reads netnames until somebody does.
- 118 prefixes for one cable footprint is decades of buying whatever blocks were available as the subscriber count grew, then announcing all of them rather than renumbering into anything tidier.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
