Unclassified RIPE
Summary
Marc Ernstberger
individual ipv6 germany
The AS handle MARCERNSTBERGER-AS is held by Marc Ernstberger.
What it's used for
- The space carries five IPv6 prefixes, including
2001:67c:2fa4::/48and four2a04:5b81blocks, with no IPv4 addresses announced. - The inventory consists of 5 IPv6 prefixes against 3 observed neighbours, a ratio consistent with a small-scale individual or hobbyist network rather than a commercial transit or access provider.
- Traffic from this AS is personal or experimental, associated with the individual operator's own infrastructure.
Notable
- The registry holder name matches the AS handle and the PeeringDB entry, confirming a single individual operator.
- The address inventory is entirely IPv6, with no IPv4 allocation, 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 2026-11-02. 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.
