Summary

Proximus Luxembourg

Luxembourg · AI-generated

business telecom luxembourg

AS-ADTS-LU is operated by Proximus Luxembourg S.A.

What it's used for

  • The address space carries corporate and financial services infrastructure, evidenced by reverse DNS entries pointing to dexia-bil.lu (Banque Internationale à Luxembourg) and netnames referencing Proximus LU NETWORK.
  • The AS announces 78080 IPv4 addresses across 4 prefixes while maintaining only 2 observed neighbours, a ratio that indicates a business or enterprise network rather than a transit provider.

Notable

  • Registrants include Proximus Luxembourg S.A., Proximus lu Internet NOC, and Banque Internationale a Luxembourg SA, aligning with the operator's identity and its major corporate clients.
  • The inventory consists of four distinct IPv4 blocks: 141.96.0.0/16, 212.63.224.0/19, 156.133.48.0/20, and 156.133.108.0/24, with no IPv6 prefixes announced.

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 1,775 prefixes, as published 2026-10-11. 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.
