Summary
CNLink
isp residential taiwan access
CNLINK-TW-AS-AP is operated by CNLink, a Taiwan-based internet service provider.
What it's used for
- The address space carries residential and small business internet access, evidenced by the netname
CNLINKTWand reverse DNS entries like1-255ip.tw.cnlink.net. - The AS announces 3,584 IPv4 addresses across 4 prefixes, with 4 observed routing neighbours. This ratio of address space to peering partners is characteristic of an access network providing last-mile connectivity rather than a transit provider.
- Traffic from this AS consists primarily of subscriber eyeballs accessing the internet, consistent with CNLink's role as a local ISP in Taiwan.
Notable
- All four announced prefixes are registered to
CNLinkunder the netnameCNLINKTW, matching the AS holder identity. - The inventory consists of four contiguous or near-contiguous IPv4 blocks within the 125.62.224.0/21 range, with no IPv6 prefixes announced.

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 2026-10-11, 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: 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
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.
