Residential ARIN Cable/DSL/ISP
Summary
C-able
cable residential isp japan
C-ABLE is operated by Yamaguchi Cable Vision Co.,Ltd.
What it's used for
- The address space carries residential cable and fiber internet services, evidenced by reverse DNS entries like
c122250032000.v4.c-able.ne.jpand netnames such asC-ABLEandC-able-CIDR-BLK-JP. - With 143,872 IPv4 addresses announced across 30 prefixes and 20 observed neighbours, the high address-to-neighbour ratio indicates an access network serving local subscribers rather than a transit provider.
Notable
- Registrants for the largest prefixes are listed as
Japan Network Information Center; IRT-JPNIC-JP, which is the regional registry rather than the operator, but the netnames consistently reference C-able. - The inventory includes a legacy
193.82.64.0/19block with the netnameYAMAGU-JPIX, alongside the primary122.250.0.0/17and122.251.0.0/17allocations. - The address inventory is finely subdivided into /20, /21, and /22 blocks, typical of a regional ISP managing distinct customer segments or service areas within Yamaguchi Prefecture.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
