Japan · AI-generated

isp residential japan cable

DODO-NET is operated by DODO K.K., a Japanese cable and DSL internet service provider.

What it's used for

  • The address space carries residential and business internet access, evidenced by the netnames NIPPONEDUIX-CIDR-BLK-JP and DODO-CIDR-BLK-JP associated with the Japan Network Information Center.
  • The AS announces 1280 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, with only 1 observed neighbour, indicating a small-scale access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for residential and small business customers in Japan, utilizing DODO's cable and DSL infrastructure.

Notable

  • Registrants for the primary prefixes align with the announcer, listing the Japan Network Information Center for 157.20.16.0/23 and 192.50.131.0/24.
  • The prefix 160.22.40.0/23 is registered to MJ TRADE AND SERVICES INDIVIDUAL ENTERPRISE with netname MTASIE-LA, which does not match the DODO K.K. identity, suggesting leased or historically allocated space.
  • The inventory is small and fragmented, with a mix of Japan-based allocations and one unrelated registrant, reflecting a niche ISP footprint.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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.
