Summary
SFR (Altice France)
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.
