Thailand · AI-generated

education university thailand

SUT-AS-AP is operated by Suranaree University of Technology.

What it's used for

  • The address space carries university infrastructure, with netnames SUOT-TH and UNINET-TH indicating Suranaree University of Technology and the Office of Info.Tech. Admin. for Educational Development.
  • The AS announces 3584 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained institutional network rather than a transit or large access provider.
  • Traffic from this AS consists of academic and administrative endpoints for the university, including research, teaching, and campus services.

Notable

  • Registrants align with the announcer for the university-owned blocks (SUOT-TH), while one prefix (58.97.61.0/24) is registered to TRUE-Corporate under TRUE IP ADMINISTRATION, suggesting leased or historically allocated space from a commercial ISP.
  • The inventory includes a mix of university-specific blocks and a commercial ISP block, reflecting a typical institutional setup where some address space is sourced from external providers.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
