Residential APNIC Cable/DSL/ISP
Summary
Obihiro City Cable
cable residential japan isp
OCTV is the AS handle for Obihiro City Cable Co.,Ltd., a regional cable operator in Hokkaido, Japan.
What it's used for
- The address space carries residential cable and DSL customer traffic, evidenced by reverse DNS entries such as
27131027254.dhcp.f1.octv.ne.jpandpc059254.dhcp.octv.ne.jp. - The AS announces 28,160 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, while maintaining 21 observed neighbours; this ratio of address space to peering partners is characteristic of an access network serving local subscribers.
Notable
- All registrants in the RDAP data are listed as Japan Network Information Center; IRT-JPNIC-JP, which is consistent with the announcer as JPNIC is the regional registry for Japan.
- The address inventory is composed of multiple /20, /21, /22, and /23 blocks, with netnames varying between
OCTV-CIDR-BLK-JPandOCTV, indicating a consolidated but historically segmented corporate estate.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
