About this network

A large Charter Communications network (TWC-11351-NORTHEAST) inherited from Time Warner Cable, now part of the Spectrum broadband footprint in the northeastern US (including the New York City metro).

What it's used for

• Cable home internet for millions of residential Spectrum subscribers across the northeastern United States.

Notable

• An "eyeball" network: addresses here are home connections, commonly behind carrier-grade NAT, not servers.
• One of the primary legacy Time Warner Cable ASNs now operated by Charter; siblings include AS10796 and AS11427.
