Summary
JCOM
cable residential isp japan
KITANET is the autonomous system for JCOM Co., Ltd., a major Japanese cable television and internet service provider.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries like
kita122050055254.kitanet.ne.jpandkita151254.kitanet.ne.jp. - With 29,696 IPv4 addresses announced across 8 prefixes and only 1 observed neighbour, the high address-to-neighbour ratio indicates this is an access network rather than a transit provider.
Notable
- All registrants for the announced prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the standard allocation process for Japanese ISPs.
- JCOM is a consolidated subsidiary of KDDI and operates as a multi-system operator (MSO) in major Japanese cities including Sapporo, Sendai, Tokyo, Osaka, and Fukuoka.
- The inventory consists of 8 IPv4 prefixes with no IPv6 prefixes announced, reflecting a legacy IPv4-centric deployment.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
