Summary

File42

Germany · AI-generated

personal ipv6 germany

FILE42 is operated by Johannes J. Jakob.

What it's used for

  • The address space consists of a single IPv6 prefix, 2001:67c:a00::/48, with no announced IPv4 prefixes.
  • The network maintains a single observed neighbour, indicating a minimal peering footprint typical of a personal or small-scale site.
  • The operator is associated with the domain file42.net and the alias Oachkatzl.net, suggesting a personal or hobbyist infrastructure project.

Notable

  • The registry holder Johannes J. Jakob aligns with the AS handle FILE42 and the web presence file42.net.
  • The inventory is limited to one IPv6 prefix, representing a small, self-contained network estate.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
