Summary

Katch Network

Japan · AI-generated

residential cable isp japan

KATCH-NET is operated by Katch Network Inc., a Japanese cable television and telecommunications provider based in Kariya, Aichi.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as d-117-74-47-254.ftth.katch.ne.jp and d-182-23-247-254.ftth.katch.ne.jp, which indicate fiber-to-the-home (FTTH) subscriber endpoints.
  • The AS announces 96,256 IPv4 addresses across 15 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour. This high address-to-neighbour ratio is characteristic of an access network aggregating local subscriber traffic rather than a transit provider.
  • Traffic from this AS consists of residential internet connectivity, cable television broadcasting, and telephone services for households in the Kariya region.

Notable

  • Registrants for the largest prefixes are listed as Japan Network Information Center (JPNIC) with netnames KATCH-NET and KATCH-CIDR-BLK-JP, consistent with the AS holder.
  • The inventory includes a mix of /18, /19, /20, and /21 blocks, with the largest being 117.74.0.0/18.
  • The single IPv6 prefix 2405:7000:400::/40 is announced alongside the IPv4 space.

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 1,784 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.
