Summary

Walailak University

Thailand · AI-generated

education university research legacy

AS9475 (WU-TH-AP) is held by Walailak University, a Thai public university in Tha Sala District, Nakhon Si Thammarat, in the country's upper south. The registry handle matches the university's own domain, wu.ac.th, and the reverse DNS confirms it.

What it's used for

This is a campus network and nothing more. The AS originates 4 IPv4 prefixes carrying 1,024 addresses — four /24s, 202.28.68.0/24 through 202.28.71.0/24 — and no IPv6. The 202.28.0.0/16 range is the block Thailand's inter-university network (UniNet, run by the Ministry of Higher Education) has historically drawn from to number member institutions, so the address holding itself places Walailak inside the Thai academic address plan rather than in commercial ISP space.

The reverse DNS on the sampled addresses resolves under wu.ac.th (hostnames such as ecom and wood), which is what you would expect: individually named servers rather than a generated pool. A single observed BGP neighbour means the university takes transit from one upstream, almost certainly its academic network provider, and does not peer independently. Together — a thousand addresses, hand-named hosts, one upstream — this is a self-run campus AS carrying the university's own staff, students and public-facing services, with no wholesale or hosting role.

Notable

  • 1,024 addresses is a small allocation for a university with several thousand students; internal networks will sit behind NAT, with the public space reserved for servers and edge services.
  • No IPv6 is announced at all, which is unusual for a research-and-education network in 2026.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
