Summary

ESIEA

France · AI-generated

education enterprise france

ESIEA is operated by Groupe ESIEA Association declaree.

What it's used for

  • The space carries the institutional network for ESIEA, a French engineering school, as indicated by the netname FR-ESIEA-20210208 and registrant Bastien Quelen; Groupe ESIEA Association declaree.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with 16 observed neighbours. This ratio of a small address block against a moderate number of peers indicates a single-site enterprise network rather than a transit or access provider.
  • Traffic from this AS consists of staff, students, and research systems associated with the ESIEA campuses in Paris and Laval.

Notable

  • The registrant Bastien Quelen; Groupe ESIEA Association declaree aligns with the AS holder and the ESIEA handle.
  • The address inventory is compact, consisting of a single /24 IPv4 block and one IPv6 prefix, consistent with a private educational institution's internal infrastructure.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
