isp residential eyeball cable fiber

NOS Comunicações (NOS) — one of Portugal's largest residential operators,

formed from the 2013 merger of ZON and Optimus.

What it's used for

  • Cable and fibre home internet, plus pay-TV and mobile, for consumers across Portugal.

Notable

  • A large Portuguese "eyeball" network: addresses here are home connections, not servers, and are often behind carrier-grade NAT.
  • Competes with MEO (Altice) and Vodafone as one of the top consumer broadband providers in the country.

Interesting

  • The "ZON" heritage comes from the cable-TV business spun out of Portugal Telecom; the Optimus merger added a mobile arm to create a full quad-play operator.
