Summary

Diatem

France · AI-generated

business enterprise france

The AS handle DIATEM is held by Diatem SAS, a French telecommunications operator based in Schiltigheim.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS entries such as rt-unccas-lille.diatem.net, fw-socomenal.diatem.net, and rt-drweb.diatem.net.
  • The AS announces 5120 IPv4 addresses across 7 prefixes while maintaining only 3 observed neighbours, a ratio that indicates an internal corporate estate rather than a public access or transit network.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing DIATEM SAS and DIATEM DBM for blocks including 95.130.152.0/21 and 185.55.144.0/22.
  • Two prefixes, 212.103.24.0/23 and 212.103.28.0/24, are registered to Completel Data NOC and SFR Tech Contact, reflecting historical ownership or leased space from the former Neuf Cegetel / LDCOM Networks.
  • One prefix, 130.117.58.0/23, is registered to Cogent Communications, LLC under the netname COGENT-EUROPEAN-OPERATIONS-001, indicating a separate allocation within the announced inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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 1,783 prefixes, as published 2026-10-20. 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.
