Summary
SFR Business Team
telecom business isp
Five company names in one inventory, one of them recorded as a parenthetical aside inside a registry contact.
What it's used for
- Business connectivity for a French carrier. 19,712 addresses in nine IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.
Notable
- The netnames span
FR-SFR-990707,FR-SFR-20051110,FR-SFR-20090202andFR-SFR-20131106. - One block is
SFR-Altice-Franceand two areFR-JET-ON-LINE, registered through aJETMULTIMEDIA NOC. - The technical contact on the 2005 block is named
SFR Tech Contact (formerly Neuf Cegetel / LDCOM Networks)— the parenthesis is part of the recorded name. - Reverse names come from two eras:
copernic-vr2177.sfr-sh.net,external-ip-212-23-183-254.sfr-sh.netandsqlsrv1-nat.jetonline.fr.
Interesting
- That contact name is the best kind of accidental documentation. Somebody updating the record could not bring themselves to discard the old names, so they appended them in brackets, and a corporate history that took three mergers now lives in a field meant to hold a person's job title.
sqlsrv1-natnames a database server and the fact that it sits behind address translation. Reverse DNS is public, so a name like that tells anyone looking what a machine is before they have to probe it — the kind of detail worth generating rather than writing by hand.- One neighbour for nearly twenty thousand addresses places this inside a larger carrier rather than at the edge of the Internet. It is a business unit's AS, reached through its parent.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
