Summary

BC-NET is operated by Benesse Corporation.
What it's used for
- The address space is registered under the netname
BENESSE-JPwith registrantIRT-BENESSE-JP, indicating a corporate internal estate. - The AS announces 2048 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a business network rather than a transit provider.
Notable
- All three announced prefixes (
182.16.236.0/22,202.8.6.0/23,202.143.2.0/23) share the same registrant and netname, confirming a unified corporate ownership. - The inventory consists of three distinct IPv4 blocks with no announced IPv6 prefixes.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,782 prefixes, as published 2026-10-16. 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.
