Summary
Noah van der Aa
research ipv6 personal
The AS handle NOAHVDAA-AS is held by Noah van der Aa.
What it's used for
- The address space consists exclusively of seven IPv6 prefixes, including
2a05:dfc1:6200::/47and2a05:dfc1:62b0::/44, with no announced IPv4 addresses. - The network maintains two observed neighbours, a ratio consistent with a small-scale research or personal infrastructure rather than a commercial transit or access provider.
- Traffic from this AS is associated with educational and research activities, as indicated by the operator's self-identification in peering databases.
Notable
- The registry holder name matches the AS handle and the operator identified in secondary sources.
- The address inventory is entirely IPv6, comprising seven distinct prefixes of varying sizes within the
2a05:dfc1::/32range.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-01, 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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
