Summary
TAS France SAS (ATSAT / Nubevia)
hosting legacy
ATSAT is the legacy handle of TAS France SAS, a French hosting and managed-infrastructure operator based in Sophia Antipolis. ATSAT was acquired and renamed TAS France, and the business now trades as Nubevia, a "sovereign" French private-cloud and managed-services provider.
What it's used for
Datacentre and cloud infrastructure, plus the connectivity that goes with it. The company is a registered French electronic-communications operator and runs or occupies facilities in Paris, Lille, Marseille, Aix-en-Provence and Sophia Antipolis. Sampled reverse DNS is all first-party router naming rather than subscriber pools: hsrp-1-th2.tasfrance.net (TeleHouse 2, a Paris carrier hotel) and hsrp-1-mil.tasfrance.net are HSRP gateway addresses, and the old brand survives on as1.atsat.com.
The AS announces around 19,200 addresses over nine IPv4 prefixes plus IPv6, and has roughly 62 observed BGP neighbours. That peering breadth is a hosting network with real interconnection, not a single-homed leaf.
Notable
- The handle, the corporate name and the trading brand are three different things:
ATSAT(registry), TAS France SAS (legal entity), Nubevia (what the website says today). hsrp-prefixes in the rDNS mean the edge is run as redundant router pairs, which is a datacentre-network fingerprint rather than an access-network one.

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.
