Summary

IFREMER (Centre de Brest)

France · AI-generated

government research legacy

The Brest research centre network of IFREMER (FR-IFREMER-BREST), the French national institute for ocean science (Institut français de recherche pour l'exploitation de la mer).

What it's used for

  • Networking for marine and oceanographic research at IFREMER's Centre de Brest in Plouzané.

Notable

  • A French public research-institution network, not a commercial ISP or host. The low AS number reflects an early allocation for national research.

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 1,784 prefixes, as published 2026-10-19. 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.
