Summary

Provincial Waterworks Authority

Thailand · AI-generated

government utility water th

PWA-AS-TH is operated by the Provincial Waterworks Authority.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname PWA-net and reverse DNS entries like dmama1.pwa.co.th.
  • The AS announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of administrative and operational endpoints for a Thai state enterprise responsible for water supply in provincial regions.

Notable

  • Registrants for both announced prefixes are Provincial Waterworks Authority with IRT IRT-PWANET-TH, matching the AS holder.
  • The Provincial Waterworks Authority is a Thai state enterprise under the Ministry of Interior, providing water services across 74 provinces.
  • The inventory consists of two contiguous IPv4 blocks: 110.76.152.0/23 and 110.76.154.0/24.

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 1,782 prefixes, as published 2026-10-16. 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.
