Summary
SFR
residential isp france mobile
The AS handle CAP-CONNEXION-AS is held by SFR (Société Française du Radiotéléphone).
What it's used for
- The address space carries SFR subscriber traffic, evidenced by reverse DNS entries such as
0.168.185.89.rev.sfr.netand netnamesFR-SFR-20060412,FR-SFR-20100422, andFR-SFR-20160503. - The AS announces 13,312 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a large access or eyeball network rather than a transit provider.
- Traffic from this AS consists of residential and mobile subscriber data, consistent with SFR's role as a major French telecommunications operator providing fixed and mobile internet services.
Notable
- Registrants for all announced prefixes list SFR SA, formerly Neuf Cegetel / LDCOM Networks, aligning with the announcer's identity.
- SFR was formed from the merger of France Télécom's mobile division and Cegetel, with the "formerly Neuf Cegetel" notation in registrant data reflecting this corporate history.
- The inventory includes a /19, a /20, and a /22 block, all registered to SFR, representing a consolidated corporate estate for its French operations.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
