Summary

  • RIPEstat lists AS131631 with the holder string AS-1033-TW - 1033 Network Information LTD.
  • The same overview places the number in the IANA 32-bit autonomous-system block 131072-132095 assigned by APNIC and marks it as announced.

1033 Network Information LTD. matters here because an autonomous system number is not just a label. An ASN is the public number a network uses when it exchanges routing information with other networks. When RIPEstat says AS131631 is announced, it means the number has a visible routing signal in the public routing view used by the service. That is stronger than a quiet registry-only record, but it is still a bounded signal.

The registry side of the record names the holder as AS-1033-TW - 1033 Network Information LTD. The allocation context places AS131631 inside the IANA 32-bit Autonomous System Numbers Registry block 131072-132095, described by RIPEstat as assigned by APNIC. APNIC is the regional internet registry for the Asia-Pacific region. In plain terms, the source ties a directory company name to a routed network identifier and to the registry block that frames the number.

The operational consequence is attribution discipline. A visible ASN can be used by analysts, network operators, customers, and security teams as a starting point for routing and registry checks. It should not be stretched into claims about the company's customers, data centers, uptime, private backbone, business health, or security posture. The useful public fact is that a named directory company is attached to an announced ASN in the current RIPEstat overview.

The technical layer is BGP, the Border Gateway Protocol that lets autonomous networks exchange reachability information. The article does not inspect individual prefixes, route paths, or RPKI records. It only records the overview fields that are present in the source: holder, block, and announced status. That narrow scope keeps the record useful without turning one registry source into a broader infrastructure profile.

The image is a generic public-domain DVIDS network-lab photograph. It supports the routing and network-infrastructure context visually, but it does not depict 1033 Network Information LTD., AS131631 equipment, customers, offices, facilities, active traffic, or reliability.
