Japan · AI-generated

gaming social business japan

GREE-NET is operated by GREE, Inc.

What it's used for

  • The address space carries corporate infrastructure for a Japanese social media and video game company, with netnames GREE, GREE-NET, and GREE-CIDR-BLK-JP registered to the Japan Network Information Center.
  • The AS announces 26,624 IPv4 addresses across 14 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, indicating a self-contained internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of web and API endpoints, game servers, and internal services supporting GREE's social networking and mobile gaming platforms.

Notable

  • All registrants are consistent with the announcer, listing the Japan Network Information Center as the registry holder for all sampled prefixes.
  • The address inventory is finely subdivided into multiple /20, /21, /22, and /23 blocks, reflecting site-by-site segmentation typical of a large corporate network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
