Summary
root S.A.
hosting legacy
ROOT is root S.A., a Luxembourg hosting company and IP transit provider. It runs one of the larger independent IP backbones in the country and is a founding member of LU-CIX, the Luxembourg internet exchange.
What it's used for
- Web hosting, dedicated and managed servers, colocation, and domain registration, plus IPv4 and IPv6 transit for other networks.
- The address space is server-side: the network fronts hosted customer machines rather than subscriber access lines.
Notable
- Luxembourg is a small country with an outsized data centre sector, and root S.A. is one of the local operators that helped establish its peering fabric rather than depending on Frankfurt or Amsterdam.
- The AS operates its own public site at
as5577.net, which is a habit of operators that expect to be looked up as a network rather than as a brand.

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
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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.
