Unclassified RIPE Non-Profit
Summary
ViaRézo
education research non-profit france
The AS handle VIAREZO is operated by ViaRézo (Association des Réseaux de CentraleSupélec).
What it's used for
- The address space carries institutional and research traffic, evidenced by the netname
ECPassociated with the registrant Centralesupelec EPSCP and the netnameIP-VRassociated with the Association des Réseaux de CentraleSupélec. - The AS announces 8,448 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 50 observed neighbours; this ratio of modest address space to a high number of peering partners indicates a transit or interconnection role rather than a large-scale access network.
- As a non-profit association supporting the network infrastructure of CentraleSupélec, the traffic consists of institutional data, research connectivity, and academic services for the engineering school.
Notable
- Registrants align with the announcer, with Centralesupelec EPSCP listed for the larger block and the Association des Réseaux de CentraleSupélec for the smaller block.
- The inventory is composed of two distinct IPv4 blocks, a /19 and a /24, alongside a single /44 IPv6 prefix, reflecting a segmented internal corporate estate.

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: 447 networks and 1,848 prefixes, as published 2026-10-31. 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.
