Summary

Taiwan, Province of China · AI-generated

business e-commerce taiwan

PUNET-AS-AP is operated by Symphox Information Co., Ltd.

What it's used for

  • The address space is registered under the netname SYMPHOX-NET across all 11 announced IPv4 prefixes, indicating a single corporate estate.
  • The AS announces 8,960 IPv4 addresses across 11 prefixes with only 2 observed neighbours, a ratio consistent with an internal corporate network rather than a transit or access provider.
  • Symphox Information provides one-stop business solutions centered on brand e-commerce, involving brand operations and data marketing, suggesting the traffic consists of office workers and web/API endpoints for its digital services.

Notable

  • All registrants align with the announcer, consistently listing Symphox Information Co., LTd. and the IRT contact IRT-PUNET-TW or IRT-SYMPHOX-TW.
  • The inventory is finely subdivided into multiple /22, /23, and /24 blocks within the 122.144.32.0/19 range, alongside three isolated /24 blocks in different /16s, reflecting site-by-site segmentation of a corporate estate.

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

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.
