Summary
Symphox Information (PUNET)
enterprise isp hosting legacy
PUNET-AP is held by Symphox Information Co., Ltd. of Taipei, a Taiwanese ISP and e-commerce/logistics technology company (the "PUNET" network). It announces about 20k IPv4 addresses across seven prefixes.
What it's used for
Reverse DNS shows both carrier backbone and hosted web/commerce content. Core routers appear as fe-12-0-0.core-a.symphox.net.tw and fe-5-1-0.core-2.symphox.net, while customer/self-hosted sites resolve directly: www.my-h2o.net, www.mygolf.com.tw, dns.holdwell.com, db.symphox.net.tw. Much of the address space follows HOST.PREFIX.symphox.com numbering. The blend of ISP backbone plus hosted commerce sites reflects Symphox's role connecting and hosting Taiwanese businesses.
Notable
- Symphox operates in Taipei, Taichung and Kaohsiung; the AS mixes its own e-commerce/logistics platforms with business connectivity rather than serving consumer eyeballs.

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: 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.
