AS9247 announces 2 IPv4 prefixes covering 4,608 addresses and 0 IPv6 prefixes.
About this network
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 155.69/16 block is legacy class-B space assigned to NTU, of which this AS announces a small slice.
