Summary

Neodyland

Japan · AI-generated

non-profit ipv6 regional

The AS handle TOKYO6TO4 WIDE Project is held by Neodyland.

What it's used for

  • The address space carries a single IPv6 prefix, 2402:2f60:c200::/48, with no IPv4 inventory.
  • With 1 announced IPv6 prefix and 2 observed neighbours, the network operates as a small-scale regional node.
  • As a non-profit organization, the traffic consists of internal organizational endpoints and project-related services rather than commercial subscriber eyeballs.

Notable

  • The registry holder is listed as BENKYO-NET, which aligns with the operator identity of Neodyland.
  • The address inventory is minimal, consisting solely of one IPv6 block, indicating a focused or experimental deployment rather than a broad commercial network.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
