Summary
Ministry of Public Health (Thailand)
government legacy
AS9649 (MOPH-TH-AP) is held by the Ministry of Public Health of Thailand — the registry object's bare "Information Technology Office" is the ministry's ICT centre at the Permanent Secretary Office in Nonthaburi. The AS originates the ministry's 203.157.0.0/16 and serves the national public-health network: the ministry itself, its departments, and the provincial hospitals and health offices under it.
What it's used for
RIS sees 14 IPv4 prefixes totalling 65,536 addresses — a full /16, deaggregated into a handful of /20s, /21s, /23s and /24s — plus a single IPv6 prefix (2001:df5:5c00::/48), announced through only 4 observed neighbours.
That is an unusually clean signature. Every announced prefix without exception falls inside 203.157.0.0/16; there is no scattered inventory, no third-party space, nothing borrowed. A single /16 held whole by one organisation and carved into internal chunks is what a national ministry looks like when it was allocated its address space directly and has run it ever since. The four upstreams are Thai carriers providing transit; with a /16 behind them and no peering breadth, none of this traffic is transiting onward. Sampled reverse DNS returns wifi.moph.go.th, an in-house .go.th government name, consistent with the space carrying ministry-operated services rather than anyone else's.
Notable
- The registry holder string names only the "Information Technology Office", which is easy to misread as a generic IT company; it is the ministry's own ICT unit.
- Thai public-hospital and provincial health-office systems commonly sit inside this /16, so the network's reach extends well beyond the ministry's head office.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
