Residential APNIC Cable/DSL/ISP
Summary
Imizu Cable Network
cable isp voip residential
The AS handle CANET is held by Imizu Cable Network Co., Ltd.
What it's used for
- The address space carries residential and VoIP traffic, evidenced by reverse DNS records such as
dhcp-133-88-59-254.voip.canet.ne.jpanddhcp-202-58-155-254.voip.canet.ne.jp. - The network announces 22,528 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining 21 observed neighbours, a ratio consistent with an access provider rather than a transit hub.
Notable
- All registrants for the announced prefixes are listed as Japan Network Information Center with the IRT-JPNIC-JP contact, which aligns with the announcer's identity as a Japanese cable operator.
- The inventory consists of ten IPv4 blocks ranging from /20 to /22 sizes, alongside a single /32 IPv6 prefix, indicating a focused regional 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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
