About this network

Fastweb is a major Italian broadband operator, known for its fibre network and owned by Swisscom.

What it's used for

• Residential fibre and fixed-wireless home internet for Italian households, plus business and mobile services.

Notable

• A large "eyeball" network: addresses here are Italian home connections, commonly behind carrier-grade NAT, not servers.
• A fibre-first challenger to the incumbent TIM that built out much of Italy's fixed-broadband and runs its own national backbone.
