About this network

An SFR network (AS21502, historically ASN-NUMERICABLE) — the cable and fibre side of SFR, France's second-largest telecom operator, built on the former Numericable cable footprint.

What it's used for

• Cable and fibre home internet for French households.

Notable

• An "eyeball" network: addresses here are residential connections, not servers.

Interesting

• SFR absorbed Numericable in the mid-2010s, folding France's largest cable network into the SFR brand.
