About this network

STPI-AS-TW is operated by National Applied Research Laboratories.

What it's used for

• The address space carries infrastructure for a national research institution, as indicated by the netname STPI-TW and the holder's identity as a government-affiliated research body.
• The AS announces 2048 IPv4 addresses within a single prefix (203.145.192.0/21) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or large-scale access provider.

Notable

• The RDAP registrant for the announced prefix is listed as unknown, while the netname is STPI-TW, which aligns with the AS handle and the registry holder name.
• The address inventory consists of a single contiguous /21 block, suggesting a consolidated internal estate for the laboratory's facilities.
