AS201911 ANDERSTB Anders T. Ballegaard
Unclassified RIPE Educational/Research
Summary
Anders T. Ballegaard
individual research ipv6
ANDERSTB is held by Anders T. Ballegaard.
What it's used for
- The space carries a single IPv6 prefix,
2a0e:97c0:ae0::/44, with no announced IPv4 addresses. - One observed neighbour against a single IPv6 prefix indicates a minimal footprint, consistent with a personal or small-scale research network rather than a commercial service provider.
- Traffic from this AS is associated with academic or research activities, as indicated by the holder's affiliation with Aarhus University and the PeeringDB classification as Educational/Research.
Notable
- The registry holder name matches the AS handle
ANDERSTB, confirming the individual ownership. - The address inventory consists solely of one IPv6 block, with no IPv4 presence, reflecting a modern, IPv6-only deployment strategy.

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 2026-11-01. 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.
