Summary
Yuan Ze University Communications Research Center
YZUCRC-NET-AP belongs to the Communications Research Center (CRC) of Yuan Ze University, a private university in Taoyuan, Taiwan, founded by the Far Eastern Group. The CRC was established in 1992, is designated a Top Research Center by Taiwan's Ministry of Education, and works on wireless and electromagnetic communications technology with about twenty faculty across seven research groups.
What it's used for
Research networking for a university lab. In RIS the AS is seen announcing no IPv4 prefixes at all and a single IPv6 /48, 2406:9dc0:1010::/48, with 1 observed BGP neighbour. That is an unusual and informative shape. A /48 is an end-site allocation, not a provider block, and a v6-only origination with one upstream is what a research group looks like when it holds an AS number for experimental or dual-stack work while its everyday IPv4 connectivity rides inside the parent university's or the national research network's address space rather than being originated here.
Notable
This is an education and research network. Nothing about the footprint fits a commercial role: there is no IPv4 to sell, no customer cone, and a single peer, so it cannot be a carrier, a hosting provider or an eyeball ISP. Read the AS as a campus research allocation and geolocate it to Yuan Ze University in Taoyuan.
Interesting
The CRC's own research is in communications technology, so an AS that exists mainly to carry an IPv6 experiment is fitting: the network is partly the object of study.

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 1,779 prefixes, as published 2026-10-21. 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.
