Summary

Japan OPS Better Co., Ltd.

Japan · AI-generated

business japan enterprise

OPSBETTER is the AS handle for Japan OPS Better Co., Ltd.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames OPSB-NET and OPSBETTER-CIDR-BLK-JP registered to the Japan Network Information Center.
  • The AS announces 1536 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale internal or business network rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints and services operated by Japan OPS Better Co., Ltd.

Notable

  • Registrants for the majority of prefixes align with the announcer, showing Japan Network Information Center as the registrant for OPSB-NET and OPSBETTER-CIDR-BLK-JP.
  • The prefix 212.74.61.0/24 is registered to TOPAPPS TECH PTE LTD with netname NET-212-74-61-0-24, which differs from the primary registrant and suggests leased or acquired address space.
  • The inventory includes a mix of Japanese and non-Japanese address blocks, with 212.74.61.0/24 being the only non-Japanese prefix in the announced set.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
