Summary

Community Network Center

Japan · AI-generated

residential isp japan broadband

CCNET-NET is operated by Community Network Center Incorporated.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as kc218-216-239-254.ccnw.ne.jp and gc49-242-151-254.gctv.ne.jp.
  • The AS announces 174080 IPv4 addresses across 33 prefixes while maintaining only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are listed as Japan Network Information Center with netnames CNCI-CIDR-BLK-JP, aligning with the announcer's identity.
  • The address inventory consists of multiple /18 and /19 blocks, including a distinct /19 block with netname HTCN-CIDR-BLK-JP at 158.199.64.0/19.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
