Summary
Kagawa Broad Network
business japan nsp
KBN is the AS handle for Kagawa Broad Network, a regional network service provider in Japan.
What it's used for
- The address space is identified by the netname
KBN-NETacross all four IPv4 prefixes, indicating a unified corporate estate. - The AS announces 10240 IPv4 addresses and 1 IPv6 prefix, with 10 observed neighbours, suggesting a role focused on serving local business or enterprise clients rather than mass residential access.
Notable
- All RDAP registrants are listed as Japan Network Information Center (JPNIC), which is standard for Japanese IP allocations and does not indicate a mismatch with the announcer.
- The inventory consists of four IPv4 prefixes and one IPv6 prefix, all registered under the same netname, reflecting a consolidated internal network structure.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
