About this network

Charter Communications (CHARTER-20115) — the US cable operator that sells home internet under the Spectrum brand.

What it's used for

• Cable home and business broadband across much of the United States.

Notable

• One of the two largest US cable ISPs (with Comcast); a major "eyeball" network of residential subscribers.
• Grew massively by acquiring Time Warner Cable and Bright House in 2016.

Interesting

• "Spectrum" is the retail brand; the underlying company and network are Charter, which is why lookups show Charter rather than Spectrum.
