Summary

Nakhon Si Thammarat University

Thailand · AI-generated

education university research

NSTRU-AS-AP is operated by Nakhon Si Thammarat University.

What it's used for

  • The address space carries university network traffic, as indicated by the netname UNINET-TH and registrant Office of Info.Tech. Admin. for Educational Development.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (202.29.33.0/24) and maintains 1 observed neighbour, a ratio consistent with an isolated academic site rather than a transit provider.
  • Traffic from this AS consists of research and educational data flows, including access to the Synchrotron Light Research Institute (SLRI) housed at the university.

Notable

  • The registrant Office of Info.Tech. Admin. for Educational Development aligns with the announcer's identity as a university network.
  • The address inventory is compact, consisting of a single contiguous /24 block with no IPv6 prefixes announced.

Reputation

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 1,772 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.

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.
