About this network

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 called DNS-TECH.
• Two blocks in 134.228 carry a netname that reads like somebody's surname.
• All eighteen sampled addresses answered, every one as cm- followed by the address, under buckeyecom.net.
• Two prefixes failed their registry lookup, so nothing is known about them here.

Interesting

• cm is 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 why 72.240.208.0 and 72.241.159.255 both 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.
