Unclassified APNIC Cable/DSL/ISP
Summary
So-net
residential isp cable dsl
SONET-TW is operated by Sony Network Taiwan Limited, widely known as So-net.
What it's used for
- The address space carries residential access traffic, evidenced by reverse DNS entries such as
adsl-tpe-NET.STATIC.so-net.net.twand219-85-127-255-adsl-KHH.dynamic.so-net.net.tw. - The network announces 320256 IPv4 addresses across 34 prefixes and 11 IPv6 prefixes, while maintaining only 9 observed neighbours, a ratio characteristic of an access/eyeball network.
Notable
- Registrants for the majority of prefixes are
IRT-SONET-TWorIRT-TWNIC-AP, with netnames consistently identified asSONET-NET. - The address inventory is finely subdivided into numerous /18, /19, and /20 blocks, reflecting site-by-site segmentation typical of a large consumer ISP.

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: 431 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.
