About this network

A Charter Communications network (TWC-11427-TEXAS) inherited from Time Warner Cable, now part of the Spectrum broadband footprint in Texas.

What it's used for

• Cable home internet for residential Spectrum subscribers across Texas markets.

Notable

• An "eyeball" network: addresses here are home connections, commonly behind carrier-grade NAT, not servers.
• One of several legacy Time Warner Cable ASNs that now roll up to Charter's Spectrum network. See sibling AS11351.
