About this network

A1 Telekom Austria (AT-AON) is Austria's incumbent telecommunications operator and the largest fixed-line broadband provider in the country, part of the A1 Telekom Austria Group.

What it's used for

• Residential fixed broadband (DSL, fibre and cable/coax) plus fixed-line voice for homes and businesses across Austria.
• Carries the national backbone that the group's fixed and mobile services ride on.

Notable

• A large "eyeball" network: most addresses here are home internet connections, not servers.
• The former state PTT and still the dominant fixed-line incumbent; A1 also runs a major mobile network, though that is largely numbered in separate ranges.

Interesting

• The "aon" handle is a legacy of Telekom Austria's original consumer internet brand from the dial-up and early DSL era.
