Summary

Association Rezel

France · AI-generated

non-profit research france

REZEL is the autonomous system for Association Rezel.

What it's used for

  • The address space carries research and academic infrastructure, evidenced by the netname FR-TELECOM-PARISTECH-20210609 associated with the prefix 195.14.28.0/24.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 47 observed neighbours; this ratio of limited address space against a high number of peers indicates a transit or interconnection role rather than a large-scale access network.
  • Traffic from this AS consists of research and educational data flows, as Association Rezel is a non-profit organization supporting the Telecom Paris site in Palaiseau.

Notable

  • Registrants for the two announced IPv4 prefixes differ: 137.194.8.0/22 is registered to Association Rezel, while 195.14.28.0/24 is registered to Institut Mines-telecom trading as Telecom Paris site de Palaiseau.
  • The inventory includes a large IPv6 block (2a09:6847::/32) alongside the smaller IPv4 allocations, reflecting a modern dual-stack research environment.

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.
