About this network

Altice USA (ALTICE-14977) — a large US cable operator serving home internet under the Optimum brand (which absorbed the former Suddenlink footprint).

What it's used for

• Residential cable and fibre home internet for millions of US households, concentrated in the New York metro tri-state area (legacy Cablevision) and Suddenlink's south-central/western markets.

Notable

• A large "eyeball" network: addresses here are US home connections, commonly behind carrier-grade NAT, not servers. Altice is one of the larger US cable ISPs behind Comcast and Charter.

Interesting

• Built from Cablevision and Suddenlink acquisitions by Altice; the Optimum and Suddenlink retail brands were unified under Optimum.
