Summary

Bank of Thailand

Thailand · AI-generated

government financial internal corporate

BOT-TH-AS is the autonomous system for the Bank of Thailand, the central bank of Thailand.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname BOTNET and reverse DNS records pointing to bot.or.th, the official domain of the Bank of Thailand.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 27 IPv6 prefixes, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio indicates an internal corporate estate with site-by-site segmentation rather than a transit or access network.

Notable

  • The registrants for both announced IPv4 prefixes are IRT-BOT-TH; Bank of Thailand, which aligns perfectly with the AS holder and the reverse DNS evidence.
  • The inventory consists of a single /23 and a single /24 in IPv4, alongside a finely subdivided IPv6 allocation under 2404:e680::/36, reflecting a structured internal network design.

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 1,779 prefixes, as published 2026-10-24. 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.
