Summary

Expressway Authority of Thailand

Thailand · AI-generated

government infrastructure corporate

EXAT-NET-TH is the autonomous system for the Expressway Authority of Thailand.

What it's used for

  • The space carries corporate network traffic for the authority, evidenced by the reverse DNS record 202-94-77-126.exat.co.th and the netname EXAT-NET-TH.
  • The AS announces 512 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal administrative and operational systems for the state enterprise responsible for building and maintaining expressways in Thailand.

Notable

  • The registrant EXPRESSWAY AUTHORITY OF THAILAND matches the AS handle and the reverse DNS domain, confirming consistent ownership.
  • The Expressway Authority of Thailand is a state enterprise under the Ministry of Transport, founded in 1972 to manage expressway infrastructure.
  • The address inventory is a single /23 block, representing a compact and self-contained corporate network.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
