Unclassified ARIN
Summary
Digital Agency
government japan gss
GSS-NET is operated by the Digital Agency of Japan.
What it's used for
- The address space carries the Government Solution Service (GSS), a shared work environment for Japanese government ministries, as indicated by the netnames
GSS-4-01andGSS-4-02. - The AS announces 9,472 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a dedicated internal network rather than a transit or access provider.
- Traffic from this AS consists of government employees and public officials accessing the GSS platform for administrative and digital services.
Notable
- Registrants for all announced prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the holder being a Japanese government entity.
- The Digital Agency was established on September 1, 2021, to strengthen digitalization in Japan, and this AS was first seen in routing tables in January 2021.
- The inventory includes a large /19 block (166.119.192.0/19) alongside smaller /23 and /24 blocks, reflecting a segmented internal 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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
