Summary
Cable Net Suzuka (MeCha / CNS)
legacy isp residential
AS9997 (MECHA) is held by Suzuka Cable Co., Ltd. — Cable Net Suzuka (ケーブルネット鈴鹿, CNS), the cable operator for Suzuka in Mie Prefecture, Japan. MeCha is the brand of its consumer internet service, which is why the handle looks nothing like the company name. Alongside it, much of the space is used by CTY, the neighbouring Mie cable operator with which CNS shares infrastructure.
What it's used for
This is one of the clearest residential access networks in the range, and the reverse DNS proves it rather than merely suggesting it. Sampled addresses resolve to names like C128H005.personal1.cable.mecha.ne.jp, C080H005.home00.cable.mecha.ne.jp and 220-219-0-5.sk.cty-net.ne.jp — per-address generated PTRs with personal, home and cable in the label, plus two-letter locality codes, which is exactly how a cable operator names subscriber CPE.
The routing matches. RIS sees 10 announced IPv4 prefixes totalling 157,696 addresses, one IPv6 aggregate (2402:700::/32), and 23 observed BGP neighbours. Two full /16s (220.219.0.0/16 and 218.226.0.0/16) anchor the pool, with /19s and /20s filling in. A large address count with a modest but non-trivial neighbour count is the signature of a regional eyeball ISP: enough peering to reach Japanese content directly at the exchanges, but nowhere near a transit carrier's adjacency count.
Notable
- The PTRs carry both
mecha.ne.jpandcty-net.ne.jpsuffixes, so this single AS serves subscribers of more than one Mie cable brand. - IPv6 is deployed and announced as a /32, which puts it ahead of many of its Asian regional-ISP peers of the same vintage.

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.
