Summary
TANet (Taiwan Academic Network)
education research legacy
TANet, the Taiwan Academic Network (ERX-TANET-ASN1), is Taiwan's national academic and research network, connecting universities, schools, and research institutions across the country.
What it's used for
- Nationwide networking for Taiwan's academic and research community, from universities down to schools.
Notable
- A national research/education backbone, not a commercial ISP. It announces a very large block of IPv4 address space.
- The
ERX-prefix marks it as an "Early Registration" record transferred from ARIN to APNIC, reflecting an early allocation.

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.
Transit providers
4 upstream, 0 downstream and 5 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,771 prefixes, as published 2026-10-15. 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.
