Summary
King Mongkut's University of Technology North Bangkok (KMUTNB)
education university research legacy
AS9533 (KMITNB-AS-AP) is held by King Mongkut's University of Technology North Bangkok, a public technical university in Bangkok specialising in engineering, technology and applied sciences. The AS handle preserves the institution's older name: it was King Mongkut's Institute of Technology North Bangkok until it was renamed and became an autonomous state university in 2007, and the KMITNB handle was never updated.
What it's used for
This is a campus network, and the routing evidence says so plainly. RIS sees 19 IPv4 prefixes carrying 4,608 addresses, with no IPv6. The structure is a single university allocation announced two ways: 202.44.32.0/20 covers the bulk of the space, and it is then deaggregated into the individual /24s (202.44.32.0/24 through 202.44.47.0/24) that sit inside it, with 202.28.17.0/24 and 202.14.164.0/24 alongside. Announcing both a covering /20 and its constituent /24s is a common way to keep reachability if one upstream path fails.
Only 2 BGP neighbours are observed. Thai universities generally connect through the national research and education network and a commercial upstream, and two neighbours on under 5,000 addresses fits exactly that: an end-user network serving students, staff, labs and campus services, buying transit rather than providing it.
Notable
- KMUTNB is one of three universities that descend from the original King Mongkut's Institute of Technology, which split into autonomous institutions in 1986. Its Thonburi sibling runs AS9551.
- The university runs campuses beyond the original Bangkok site, which is consistent with the several separate /24 blocks.

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 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
