Unclassified ARIN
Summary
MAFFIN
government research network
MAFFIN is the research network operated by the Ministry of Agriculture, Forestry and Fisheries of Japan.
What it's used for
- The space carries the ministry's research infrastructure, identified by the netname
JAPAN150and the registry handleMAFFIN Ministry of Agriculture, Forestry and Fisheries Research Network. - It announces 65536 IPv4 addresses across a single /16 prefix (150.26.0.0/16) and maintains 14 observed neighbours, a ratio consistent with a dedicated institutional network rather than a transit provider.
Notable
- The RDAP registrant for the announced prefix is
IRT-JPNIC-JP(Japan Network Information Center), which is the standard registry for Japanese address space and aligns with the Japanese government holder. - The address inventory consists of a single contiguous /16 block, indicating a unified internal estate for the ministry's operations.

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 1,771 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.
