Summary

Dominik Kupschke

Germany · AI-generated

research ipv6 germany

The AS handle KUPSCHKE is held by Dominik Kupschke.

What it's used for

  • The space carries a single IPv6 prefix, 2a0f:85c1:d67::/48, with no IPv4 addresses announced.
  • One IPv6 prefix against two observed neighbours indicates a small-scale network, consistent with an individual or small research setup rather than a commercial ISP.
  • Traffic from this AS is associated with educational or research activities, as indicated by the operator's self-description and website content.

Notable

  • The registry holder and AS handle both identify Dominik Kupschke, confirming alignment between the registrant and the announcer.
  • The address inventory consists solely of one IPv6 /48 block, representing a minimal footprint typical of a personal or academic project.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
