APBW-AS-TW is the autonomous system for Asia Pacific Broadband Wireless Communications Inc.

What it's used for

  • The address space carries mobile broadband traffic, evidenced by the reverse DNS record 203-201-34-254.mobile.dynamic.aptg.com.tw and netnames such as APBW-NET and FET.
  • The AS announces 7168 IPv4 addresses across 21 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio characteristic of an access network rather than a transit provider.

Notable

  • Registrants include IRT-FET-TW for the primary APBW-NET and FET blocks, alongside unrelated entities like SRI International and APNIC for smaller leased or historical allocations.
  • The inventory consists of a mix of /22, /23, and /24 blocks, with the largest being 203.201.32.0/22, indicating a segmented corporate and customer estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
