isp residential eyeball cable fiber dsl backbone

SFR (LDCOMNET / Numericable-SFR, part of Altice France) — one of France's

largest telecom operators and residential-broadband providers.

What it's used for

  • Residential DSL, coax cable (former Numericable) and FTTH fibre home internet across France, plus a national backbone.

Notable

  • A large "eyeball" network: addresses here are French home connections, not servers. SFR is a top-tier French fixed+mobile operator alongside Orange, Free (Iliad) and Bouygues.

Interesting

  • Formed by the merger of Numericable's cable network with SFR under Altice; the ASN carries legacy LDCOM/Numericable heritage.
