AS38656 LOUTRES Loutres
Unclassified APNIC
Summary
Loutres
education research japan
The AS handle LOUTRES is operated by Loutres.
What it's used for
- The address space carries the netname
LTRS-NET01, registered with the Japan Network Information Center. - The network announces 512 IPv4 addresses within a single /23 prefix and one IPv6 /48 prefix, while maintaining 4 observed routing neighbours.
- PeeringDB classifies the operator as an Educational/Research entity, indicating the traffic consists of academic and research endpoints rather than commercial subscriber eyeballs.
Notable
- The RDAP registrant for the announced prefix is the Japan Network Information Center, which is consistent with the AS holder being a Japanese entity.
- The address inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a dedicated institutional network.

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.
