Summary
MARU (OTO GK)
network legacy
MARU-NET is held by OTO GK, a Japanese company operating a small network under the MARU name. The AS number is a reissue: the registration dates to 2026, so despite the low number this is a modern holder with no early-internet pedigree.
What it's used for
- MARU describes itself in peering records as a network service provider in the Asia-Pacific region with an open peering policy.
- What it actually announces is modest: two
/24s re-registered asMARU-CIDR-BLK-JP, plus a large IPv6/29. Its published site was still a placeholder at the time of writing.
Notable
- The registry paperwork is unusual. A Japanese organisation holds the AS and its address blocks through RIPE rather than APNIC, and the IPv6
/29is registered to a separate individual, with only a MARU remark linking them. - The IPv4 blocks are recycled legacy space, not a fresh allocation — a common pattern for small networks assembled out of transferred address blocks.
- Because the self-description (a regional network service provider) is far larger than the inventory it announces, this network is best treated as unclassified rather than forced into a category.

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 1,779 prefixes, as published 2026-10-21. 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.
