About this network

Frontier Communications (FRONTIER-FRTR) is a large US residential and small-business ISP, running legacy DSL alongside a growing fibre footprint.

What it's used for

• Home internet across many US states: DSL over former incumbent copper plus expanding FTTH fibre.

Notable

• An "eyeball" network: addresses here are US home connections, not servers.
• Frontier grew by acquiring rural and suburban telephone lines (including former Verizon and AT&T territories) and is now investing heavily in fibre after a Chapter 11 restructuring.

Interesting

• Its mix of aging copper DSL and new fibre makes Frontier's footprint unusually uneven, varying block-by-block across its many acquired service areas.
