Summary
National Institute of Education (NIE), Singapore
education university research legacy
AS9247 (NIE-SG) is held by the National Institute of Education, Singapore's teacher-education institute and an autonomous institute of Nanyang Technological University. NIE trains the country's teachers and school leaders and runs education research alongside that mission.
What it's used for
This is a campus network. RIS sees 3 IPv4 prefixes carrying 4,608 addresses — a 155.69.64.0/20 plus two /24s at 155.69.96.0 and 155.69.97.0 — with no IPv6 announced and only 2 observed neighbours.
The address block is the most informative part. 155.69.0.0/16 is Nanyang Technological University's space, and NIE's announcement is a carved-out piece of it: the institute has its own autonomous system and originates its own subnets, but the addressing comes from the parent university's legacy /16 rather than a separate allocation. That is a common arrangement where an institute is administratively distinct enough to want its own routing policy while remaining part of the university's address estate.
Two neighbours and under five thousand addresses is a small, self-contained network: campus users, institute services, and research systems, reached through a couple of upstreams. There is no customer space and no transit role here. The IPv4-only announcement is worth noting for an academic network, since research and education networks are usually early IPv6 adopters — any IPv6 NIE uses appears to be routed through the parent university rather than originated from this AS.
Notable
- NIE is an autonomous institute of NTU, so the university's network and NIE's overlap; do not read this AS as covering all of NTU.
- The
155.69/16block is legacy class-B space assigned to NTU, of which this AS announces a small slice.

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 1,771 prefixes, as published 2026-10-15. 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.
