Summary

E-SI

France · AI-generated

datacenter business france

The AS handle E-SI is held by E-SI EURO SYSTEME D'INFORMATION SASU.

What it's used for

  • The address space carries datacenter and corporate infrastructure, evidenced by the netname FR-E-SI-20160301 and reverse DNS entries pointing to rev.e-si.fr and rev.groupe-capelle.net.
  • The network announces 1280 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small-scale business or datacenter presence rather than a transit or large access network.
  • Traffic from this AS consists of web and API endpoints for the operator's datacenter services and the Capelle group's corporate infrastructure.

Notable

  • Registrants align with the announcer, listing E-SI - DATACENTER and CAPELLE Investissements SA for the respective prefixes.
  • The inventory is split between two distinct entities: E-SI's own datacenter space and a block registered to Capelle Investissements SA, suggesting a corporate relationship or lease arrangement.
  • The address inventory is compact, consisting of one /22 and one /24 block, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
