SMCI-AS-TW is the autonomous system for Super Micro Computer, Inc.

What it's used for

  • The address space carries corporate infrastructure for a server and storage hardware manufacturer, identified by the netname SMCI-NET and registrant IRT-SMCI-TW.
  • The AS announces 512 IPv4 addresses within a single prefix (103.162.84.0/23) and maintains 2 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access network.
  • Traffic from this AS represents office workers, engineering staff, and data center endpoints for a company that designs and manufactures high-performance computing systems.

Notable

  • The registrant IRT-SMCI-TW and netname SMCI-NET align directly with the AS holder, Super Micro Computer, Inc.
  • Super Micro Computer, Inc. is an American information technology company based in San Jose, California, with significant manufacturing operations in Taiwan.
  • The inventory consists of a single contiguous IPv4 block with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
