Optimum

OPTIMUM is a U.S. telecom brand tied to Optimum Communications, Inc. (formerly Altice USA), which provides residential and business connectivity services under the same consumer-facing name. Public materials and third-party summaries consistently associate the brand with cable broadband and related voice/TV offerings.

Routing and IP footprint commonly map to AS6128 (Cablevision Systems Corporation / Altice USA) in ASN directories and BGP trackers, and PeeringDB lists AS6128 as a peering participant. Public IP/ASN datasets show large U.S.-centric address space under this ASN; beyond that, externally verifiable detail varies by region and product line.

Across major review aggregators (for example Trustpilot and ConsumerAffairs) and multiple third-party ISP review sites, user feedback trends negative, with frequent complaints about support and billing; positive reports exist but appear less common in aggregated ratings.
