business infrastructure japan

The AS handle GMO-REG-NET is held by GMO Internet Group, Inc.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the netname GMOREG-JPSRS and reverse DNS entries pointing to undefined.gmointernet.com.
  • 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 access network.
  • Traffic from this AS consists of internal services and infrastructure endpoints for GMO Internet Group, a Japanese company providing internet infrastructure, advertising, and financial services.

Notable

  • The RDAP registrant for the announced prefix is Japan Network Information Center (JPNIC), which is the standard registry for Japanese IP space, while the AS holder is GMO Internet Group, Inc.
  • GMO AD Partners Inc. changed its company name to GMO Internet, Inc. as of January 1, 2025.
  • The address inventory is a single /24 block, consistent with a specific internal segment of the corporate estate.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
