Education APNIC
Summary
Temasek Polytechnic
education legacy
AS9292 (TEMASEKPOLY-SG) is held by Temasek Polytechnic, a post-secondary institution and statutory board under Singapore's Ministry of Education. The registry object shows a street address — "21 Tampines Avenue 1" — rather than an organisation name; that is the polytechnic's campus in Tampines, and the handle confirms it. This is a single-campus network.
What it's used for
Everything the AS announces comes out of one legacy block, 152.226.0.0/16. It originates 15 IPv4 prefixes from it — five /20s, two /21s and a handful of /24s — totalling roughly 26,624 addresses, with no IPv6 announced. Only two BGP neighbours are observed. Two upstreams and no peering breadth is the signature of an end site: an institution buying redundant transit, not an operator selling anything. The internal deaggregation into /20s is campus structure being exposed to the routing table rather than customer assignment. The address count is large relative to the size of a polytechnic, but that is an artefact of holding a legacy class-B-era block from the early 1990s rather than a measure of how many devices are actually online.
Notable
- The whole footprint sits inside a single
/16, so152.226.0.0/16can be treated as institutional Singaporean education space. - No IPv6 is announced at all, which is worth flagging for an education network in a country with high v6 deployment elsewhere.
- Traffic from this AS is students, staff, labs and campus services. There is no hosting, transit or commercial function here, and the holder name in most databases will not obviously read as a school.

Internet exchanges
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: 442 networks and 1,773 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.

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.
