GMO-DNS is operated by GMO Internet Group, Inc.
What it's used for
- The address space is registered under the netname
GMO-CIDR-BLK-JPwith the Japan Network Information Center, indicating a corporate infrastructure allocation. - The AS announces 1024 IPv4 addresses within a single /22 prefix and 3 IPv6 prefixes, while maintaining only 3 observed routing neighbours.
- As a major Japanese internet infrastructure provider, this space supports the company's internal services, including domain registration, cloud hosting, and security platforms.
Notable
- The RDAP registrant is the Japan Network Information Center, which is consistent with the Japanese origin of the address block and the operator's location.
- The inventory consists of one contiguous IPv4 block and three distinct IPv6 /48 prefixes, reflecting a standard corporate address plan.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,843 prefixes, as published 2026-11-01. 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.
