Summary

Singapore Management University

Singapore · AI-generated

education business university

SMU-AS-AP is the autonomous system for Singapore Management University.

What it's used for

  • The address space is registered under the netname SMUSG with registrant Singapore Management University, indicating a dedicated institutional network.
  • The AS announces 8192 IPv4 addresses within a single prefix (202.161.32.0/19) and maintains 2 observed neighbours, a ratio consistent with an internal corporate or educational estate rather than a transit provider.

Notable

  • The RDAP registrant Singapore Management University aligns directly with the AS holder Office of Communications & IT, confirming the space belongs to the university's internal infrastructure.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a standard on-premises network configuration for a campus environment.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
