Summary

Square Enix

Japan · AI-generated

business gaming japan corporate

POLEXCHENGE is the autonomous system handle for Square Enix Co., Ltd., a major Japanese video game publisher and developer.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames SQUARE-POL and SQUARE-ENIX registered to the Japan Network Information Center.
  • The AS announces 18,432 IPv4 addresses across 12 prefixes with only 1 observed neighbour, indicating a closed internal corporate estate rather than a transit or access network.

Notable

  • All registrants are the Japan Network Information Center, consistent with the announcer's identity as a Japanese entity.
  • The netnames reflect the company's history, combining the legacy "Square" and "Enix" brands following their 2003 merger.
  • The inventory consists of finely subdivided blocks, including /20, /21, /22, and /23 prefixes, typical of site-by-site segmentation for a large corporation.

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 1,783 prefixes, as published 2026-10-17. 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.
