Summary
CoreSystem
transit isp france
CORESYSTEM is operated by CoreSystem SASU.
What it's used for
- The address space carries infrastructure and service endpoints, evidenced by reverse DNS entries such as
ae0-96-i4k-01-nce.coresystem.netandweb190-vip.poneyserver.com. - The AS announces 512 IPv4 addresses across 2 prefixes and 16 IPv6 prefixes, while maintaining 11 observed neighbours. This ratio of limited address inventory to a moderate number of peering partners indicates a transit or network service provider role rather than a large-scale access network.
- As a network service provider, traffic from this AS consists of upstream transit, inter-AS routing, and connectivity for its customer base.
Notable
- Registrants for both announced IPv4 prefixes are listed as
CORESYSTEM NOC; CORESYSTEM SASU, which aligns directly with the AS holder. - The address inventory is compact, consisting of two /24 IPv4 blocks and a set of IPv6 prefixes under the
2a10:8b40::/36range.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
