Summary
nLighten France
isp residential france nsp
The AS handle NLT-FR is held by nLighten France SAS, a regional network service provider in France.
What it's used for
- The address space carries residential and business connectivity, evidenced by netnames such as
FR-EUCLYDE-20021128andFR-EUCLYDE-20190204associated with the registrant nLighten France SAS. - The AS announces 6400 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining 8 observed neighbours; this ratio of address space to peering partners is consistent with an access or eyeball network role.
Notable

193.135.126.0/24and193.218.120.0/24) are registered to PROXIDESK SARL and ICS SA respectively, indicating leased space or historical acquisitions. - The operator was formerly known as Euclyde, as indicated by the netnames and secondary sources describing the entity as "nLighten France (aka Euclyde)".
- The inventory includes a mix of /20, /23, and /24 blocks, with the largest being
217.13.48.0/20.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
