Summary
King Mongkut's University of Technology Thonburi (KMUTT)
education university research legacy
AS9551 (KMUTT-AP) is held by King Mongkut's University of Technology Thonburi, a public research university in Bangkok known for engineering and technology. It is one of three autonomous institutions that descend from the original King Mongkut's Institute of Technology, which split in 1986; its North Bangkok sibling runs AS9533.
What it's used for
This is a campus network and nothing else. RIS sees 13 IPv4 prefixes carrying 3,328 addresses, every one of them a /24, and no IPv6 at all. The space clusters in two runs: 202.44.8.0/24 through 202.44.15.0/24, and 202.28.4.0/24 through 202.28.7.0/24, with 49.231.233.0/24 alongside.
Those two ranges are the tell. 202.28.0.0/16 and 202.44.0.0/16 are shared Thai higher-education blocks, allocated centrally and subdivided among member institutions — the same ranges appear under KMUTNB's AS9533 and under Khon Kaen University's AS9546. A university announcing a handful of /24s carved from a national academic block is the standard Thai pattern, and announcing them individually rather than as an aggregate reflects the fact that they were never one contiguous allocation to begin with.
Only 2 BGP neighbours are observed. Two upstreams on 3,328 addresses is an end-user network: it buys connectivity, most likely from the national education and research network plus a commercial carrier, and serves its own students, staff, labs and campus systems.
Notable
- KMUTT is a research-intensive university, so this space fronts laboratory and research systems as well as ordinary campus services.
- No IPv6 is announced, which is common among the Thai academic ASes in this range.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
