Residential RIPE
Summary
SFR (Numericable)
isp residential eyeball cable fiber
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.
- SFR is a fixed + mobile operator; it runs several ASNs, with this block carrying the legacy Numericable cable/FTTH subscriber base.
Interesting
- SFR absorbed Numericable in the mid-2010s, folding France's largest cable network into the SFR brand.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,845 prefixes, as published 2026-10-31. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
