cable residential japan access

KGC-NET is operated by Koga Cable TV Co., Ltd.

What it's used for

  • The space carries cable television subscriber traffic, evidenced by the reverse DNS record 254.155.3.202.ca03st.rcctv.jp which indicates customer premises equipment on a cable network.
  • The AS announces 4096 IPv4 addresses within a single prefix (202.3.144.0/20) and maintains only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of residential broadband subscribers accessing the internet via the company's cable infrastructure in Koga, Japan.

Notable

  • The RDAP registrant for the announced prefix is Japan Network Information Center (JPNIC), which is the standard registry for Japanese IP space and aligns with the local operator.
  • The address inventory is compact, consisting of a single /20 block, which is typical for a regional cable operator serving a specific municipality.

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 1,845 prefixes, as published 2026-10-31. 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.
