Summary
DWINS Digital Service Corp.
business taiwan digital
DWINS-TW is the AS handle for DWINS Digital Service Corp.
What it's used for
- The address space carries digital services, evidenced by the reverse DNS record
ms254.ezmail.com.twfound in the sample. - The AS announces 8192 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that suggests an internal corporate estate or limited access network rather than a transit provider.
Notable
- The registrants for both announced prefixes,
112.213.48.0/20and211.78.80.0/20, areIRT-DWINS-TW, which aligns perfectly with the announcer. - The address inventory consists of two /20 blocks, both registered under the netname
DWINS-TW, indicating a consolidated and self-contained IP 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
1 upstream, 0 downstream and 1 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 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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 |
|---|---|---|
211.78.84.17 | 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.
