What it's used for
- The address space carries corporate IT infrastructure, evidenced by reverse DNS entries such as
128.rsix.ad.jpandb126.rsix.ad.jpunder the netnameRIDC-NET. - The network announces 512 IPv4 addresses and 3 IPv6 prefixes with 4 observed neighbours, a ratio consistent with a business network providing IT services and data center operations rather than residential access or transit.
- Traffic from this AS consists of web/API endpoints and internal corporate systems supporting Ryobi Systems' business in system development, outsourcing, and data center operations for public and private sectors.
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 announcer's location.
- The address inventory consists of a single IPv4 prefix (103.239.90.0/23) and three IPv6 /48 prefixes, indicating a compact, internally managed corporate estate.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
