Unclassified RIPE
Summary
Kitaura Hana Net
nonprofit small jp
AIN-NET is the AS handle for Kitaura Hana Net, a Japanese nonprofit organization.
What it's used for
- The address space is registered under the netname
AIN-HANA-CIDR-BLK-JP, indicating a dedicated allocation for the organization. - The AS announces 1792 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio consistent with a small, isolated network rather than a transit or large access provider.
Notable
- The RDAP registrants for all announced prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which is the standard registry for Japanese IP space and does not contradict the announcer's identity.
- The inventory consists of three blocks: 203.192.96.0/22, 203.192.100.0/23, and 203.192.103.0/24, all located in Japan.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
