Network type: education

AS9486 announces 1 IPv4 prefixes covering 65,536 addresses and 0 IPv6 prefixes.

About this network

AS9486 (KMITL-AP) is held by King Mongkut's Institute of Technology Ladkrabang, a public research university in the Lat Krabang district on the eastern edge of Bangkok. KMITL is one of Thailand's principal engineering and technology institutions, with faculties spanning engineering, architecture, science, IT, agricultural technology and medicine.

What it's used for

The routing table makes this an unusually clean case: the AS originates 65,536 IPv4 addresses from just 2 prefixes — 161.246.0.0/16 and a /17 covering its lower half. That is a full legacy class-B, held and announced by the institute itself. The /17 alongside the /16 is a routine more-specific, typically used to steer part of the campus over a different upstream or to blunt hijacks of the covering aggregate.

Two observed BGP neighbours and no IPv6. A network holding 65k addresses with two peers is not a carrier of any kind: the address count comes from an early allocation, not from scale of transit business. This is a self-numbered campus AS carrying the institute's own staff, students, labs and public-facing services, taking transit from its academic upstream (Thai universities are generally fed by UniNet) and originating one aggregate for the whole campus.

Notable

• A /16 for a single campus is a marker of an early allocation. Address blocks that size were routinely handed to universities in the pre-CIDR-scarcity era and are rarely reissued today.
• The complete absence of an IPv6 announcement is notable for a research-and-education network.
