Summary
Optimum (Cablevision)
isp residential eyeball cable
CABLE-NET-1 is the former Cablevision network, now Optimum, a major cable broadband provider
in the US Northeast owned by Altice USA.
What it's used for
- Home internet across the New York metro area and surrounding Northeast: cable (DOCSIS) and fibre for households under the Optimum brand.
Notable
- An "eyeball" network: addresses here are US home connections, commonly behind carrier-grade NAT, not servers.
- Cablevision was the dominant cable operator in the New York suburbs; Altice acquired it and rebranded it Optimum, which sits alongside Altice's Suddenlink (also now Optimum) footprint.
Interesting
- The New York tri-state area it serves is one of the densest consumer broadband markets in the United States.
