The AS handle CORESYSTEM-LABS is held by CoreSystem SASU.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname FR-CORESYSTEM-20230307 and registrant CORESYSTEM NOC; CORESYSTEM SASU.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained network rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for the CoreSystem organisation, located in Nice, France.

Notable

  • Registrants align with the announcer, listing CORESYSTEM NOC and CORESYSTEM SASU for the announced prefix.

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 1,781 prefixes, as published 2026-10-16. 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.
