Summary
Aperture Networks
research education netherlands
APERTURE-NETWORKS is operated by Aperture Networks.
What it's used for
- The address space carries research and educational traffic, as indicated by the PeeringDB classification of "Educational/Research" and the netnames
APERTURE-NETWORKSandRoelf-Wichertjes. - The AS announces 512 IPv4 addresses across 2 prefixes and 50 IPv6 prefixes, while maintaining 34 observed neighbours. This ratio of modest address space to a significant number of peering partners suggests a network focused on connectivity and exchange rather than large-scale residential access.
- Traffic from this AS consists of academic and research endpoints, consistent with the operator's stated scope and the presence of a dedicated NOC contact.
Notable
- Registrants for both announced IPv4 prefixes are listed as Roelf Wichertjes, aligning with the registry holder and the AS handle
APERTURE-NETWORKS. - The IPv6 inventory is finely subdivided into 50 distinct prefixes, indicating a structured internal allocation strategy for the research network.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
