Summary

CRCCMedia

Japan · AI-generated

residential cable japan access

The AS handle CRCC is held by CRCCMedia Co.,ltd.

What it's used for

  • The address space carries residential cable access traffic, evidenced by reverse DNS entries such as pc-202-55-200-0.cable.kumin.ne.jp and pc-202-169-136-0.cable.kumin.ne.jp.
  • The network announces 16384 IPv4 addresses across 2 prefixes, with only 1 observed neighbour, indicating a local access network rather than a transit provider.

Notable

  • The registrants for both prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the Japanese allocation authority for the space.
  • The inventory consists of two /19 blocks, 202.55.192.0/19 and 202.169.128.0/19, both located in Japan.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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.
