Unclassified RIPE Educational/Research
Summary
GEANT
education research transit netherlands
The AS handle GEANT is held by GEANT Vereniging.
What it's used for
- The address space carries research and education infrastructure, evidenced by netnames
NL-GEANT-20010717andGEANT_IAS_VRFand reverse DNS entries liketest.nmaas.geant.organdtest-a10-controller01.geant.org. - The AS announces 9,216 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 72 observed neighbours; this ratio of moderate address space to high peering density indicates a transit or backbone role for the European research network.
Notable
- Registrants for both announced prefixes are consistent with the announcer, listing GEANT Operations, GEANT Vereniging, and GEANT CERT (formerly DANCERT).
- The address inventory consists of two distinct IPv4 blocks, 62.40.96.0/19 and 83.97.92.0/22, alongside a single IPv6 prefix, 2001:798::/31.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
6 upstream, 57 downstream and 117 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
