Summary
Government Service Network (GSN), Taiwan
government legacy
GSNET — Taiwan's Government Service Network (GSN), operated by the Data Communication Business Group of Chunghwa Telecom on behalf of the government.
What it's used for
- A national backbone connecting central and local government agencies in Taiwan.
- Shared services for the public sector: agency email and internet access, directory services, and the network underlay for e-government systems such as tax and vehicle/driver registration platforms.
Notable
- GSN was built in 1997 to give government agencies a common, independently managed network environment with its own security posture, rather than having each agency buy connectivity separately.
- It reaches tens of thousands of access lines across government, and also supports disaster response and traffic monitoring systems.
Interesting
- The holder, Chunghwa Telecom's Data Communication Business Group, is the same business unit that runs HiNet — but AS4782 is the government network, not the commercial consumer ISP. Do not read a GSN address as a HiNet broadband subscriber.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
117.56.214.246 | Chinese Government-linked Cyber Threat Actors Combine Automated and Hands-on Hacking Tools to Steal Sensitive Data | 2026-10-08 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
