Interesting
e.V.marks an eingetragener Verein, a registered association under German law. It is the legal form clubs, societies and community projects take, and it appears in the routing table more often than one might expect: the internet's early German build-out ran substantially through associations rather than companies.- Eighteen neighbours on 512 addresses inverts the usual ratio. A network with almost no address space and a great deal of interconnection is not serving subscribers; it is somewhere other networks meet, or it is run by people who peer because peering is the interesting part.
- The /40 in IPv6 is 65,536 times the address space of the /23 in IPv4, and it is a small IPv6 allocation. The two protocols are not measured on the same scale, and comparing prefix lengths across them is a reliable way to be wrong about a network's size.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
