Residential APNIC Cable/DSL/ISP
Summary
Digital United (SEEDNet)
isp legacy
SEEDNET — the network of Digital United Inc., operator of SEEDNet, one of Taiwan's largest and longest-running internet service providers.
What it's used for
- Consumer and business internet access across Taiwan, including broadband subscribers.
- Peering and transit for the SEEDNet network.
Notable
- SEEDNet has long been among Taiwan's biggest ISPs, second in scale mainly to Chunghwa Telecom's HiNet.
- Digital United was folded into the Far Eastern Telecom Group; SEEDNet today sits under New Century InfoComm Tech, part of the Far EasTone group.
- With over 1.5 million IPv4 addresses this is a genuine eyeball network — most of the space terminates on subscribers.
Interesting
- Taiwan's ISP market concentrated heavily over the years, and SEEDNet is a good example: an independent provider that kept its brand and its ASN while its ownership moved under a mobile carrier group.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,769 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
2 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
210.243.225.41 | Chinese Government-linked Cyber Threat Actors Combine Automated and Hands-on Hacking Tools to Steal Sensitive Data | 2026-10-08 |
210.66.220.39 | 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.
