Summary

GMO Internet Group

Japan · AI-generated

business infrastructure japan

GMO-REGSEC is held by GMO Internet Group, Inc.

What it's used for

  • The space carries infrastructure for a major Japanese internet services provider, as indicated by the netname GMOREG-JPSRS and registrant Japan Network Information Center.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix with only 1 observed neighbour, indicating a small, self-contained internal estate rather than a transit or large access network.
  • Traffic from this AS consists of internal corporate infrastructure and services for GMO Internet Group, a company that develops internet infrastructure, security, and online advertising.

Notable

  • Registrants align with the announcer, with Japan Network Information Center listed for the announced prefix.
  • The address inventory is minimal, consisting of a single /24 block and one /48 prefix, consistent with a specific internal segment of a larger corporate network.

Reputation

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
