research ipv6 germany

AGL-DIVISION-AS is held by Julian Kuhn.

What it's used for

  • The address space consists entirely of IPv6 prefixes, including 2a0f:b240:7c00::/47 and 2a0f:b240:7c80::/41, with no IPv4 inventory.
  • The AS announces 8 IPv6 prefixes and maintains 8 observed neighbours, a ratio that suggests a small-scale research or educational network rather than a transit provider.
  • PeeringDB classifies the operator as Educational/Research, and the associated website secshell.de indicates a focus on security research.

Notable

  • The registry holder JULIANKUHN matches the AS name, confirming direct ownership.
  • The address inventory is exclusively IPv6, comprising eight distinct prefixes within the 2a0f:b240::/32 range.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
