Summary
National Health Research Institutes
research government business other
NHRINET is operated by National Health Research Institutes.
What it's used for
- The address space carries internal network infrastructure for a medical research institution, evidenced by the netname
NHRI-NETand reverse DNS records pointing tonhri.org.tw. - The AS announces 4096 IPv4 addresses within a single /20 prefix (211.76.160.0/20) and maintains 3 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access provider.
Notable
- The RDAP registrant
National Health Research Institutes Administratoraligns directly with the AS holder and theNHRINEThandle. - The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a focused internal network footprint.

Interconnection
Peering at a glance
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 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
