KCV-HitaNet is operated by KCV Communications Co. Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS names such as pc6-69-0.b-net.kcv.jp and cl11-254.b-net.kcv.jp across all announced prefixes.
  • The AS announces 6,656 IPv4 addresses across 4 prefixes and maintains 13 observed neighbours, a ratio consistent with an access network providing last-mile connectivity.
  • Traffic from this AS consists of subscriber eyeballs for cable and DSL services, as indicated by the operator's classification as a Cable/DSL/ISP.

Notable

  • Registrants for all prefixes are listed as Japan Network Information Center (JPNIC) with netnames KCV-NET or KCV-NET-CIDR-BLK-JP, aligning with the announcer KCV Communications.
  • The inventory consists of four distinct IPv4 blocks, including a /20 and three smaller /22 and /23 prefixes, with no IPv6 prefixes in inventory.

Reputation

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.
