Summary

SAKURA Internet

Japan · AI-generated

cloud hosting vps

A sibling Autonomous System of SAKURA Internet, a major Japanese hosting and cloud provider (SAKURA-B). It carries the same kind of hosting, VPS, and cloud traffic as the operator's main network.

What it's used for

  • Hosting websites, VPS, dedicated servers, and cloud instances out of Sakura's Japanese data centers.

Notable

  • An IP here identifies Sakura as the host, not the operator of whatever runs on it.
  • See the primary Sakura card AS7684 and the other sibling AS9371.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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.
