Summary

ICKNET

Japan · AI-generated

cable isp residential japan

ICKNET is operated by Imabari CATV Corporation.

What it's used for

  • The address space carries residential cable broadband traffic, evidenced by reverse DNS entries like dh109254.icknet.ne.jp and dh170254.icknet.ne.jp which indicate dynamic host assignments for end-user devices.
  • The network announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, maintaining 5 observed neighbours; this ratio of address space to peering partners is characteristic of a local access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs accessing the internet via cable modem connections in the Imabari region of Japan.

Notable

  • Registrants for both announced prefixes are listed as Japan Network Information Center with the netname ICK-NET, consistent with the holder identity.
  • The address inventory is compact, consisting of one /21 and one /22 block, reflecting the limited geographic scope of a single municipal cable operator.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
