Unclassified APNIC
Summary
Singapore University of Technology and Design
education university research
The AS handle SUTD-SG is operated by Singapore University of Technology and Design.
What it's used for
- The address space carries university infrastructure, with reverse DNS pointing to
elearning.sutd.edu.sgfor both announced prefixes. - The network announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, indicating a small, self-contained institutional network rather than a transit or large-scale access provider.
- Traffic from this AS consists of academic and research endpoints, including e-learning platforms and administrative services for the university community.
Notable
- Registrants for both prefixes are consistent with the announcer, listing "SINGAPORE UNIVERSITY OF TECHNOLOGY AND DESIGN" with netnames
SUTD-AS-APandSUTD-SG. - The address inventory is compact, comprising two /24 blocks (103.24.77.0/24 and 202.94.70.0/24) with no IPv6 prefixes in inventory.

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 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 449 networks and 1,846 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
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.
