Summary

Alex Wellnitz

Germany · AI-generated

personal ipv6 germany

The AS handle DEV-NULL is held by Alex Wellnitz.

What it's used for

  • The space carries a single IPv6 prefix, 2a06:9801:5a::/48, with no IPv4 addresses announced.
  • The inventory consists of 1 IPv6 prefix against 2 observed neighbours, indicating a small-scale network with limited peering.
  • Traffic from this AS is associated with the personal website alexohneander.de, suggesting individual or hobbyist internet usage rather than commercial service provision.

Notable

  • The registry holder is listed as "DEV-NULL Alex Wellnitz", aligning with the AS name and the individual identified in secondary sources.
  • The address inventory is minimal, consisting solely of one IPv6 block, which fits the profile of a personal or small-scale network rather than an enterprise or ISP.

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.
