Summary

Ramkhamhaeng University

Thailand · AI-generated

education university th

RAMKHAMHAENG-AS-AP is operated by Ramkhamhaeng University.

What it's used for

  • The address space carries the university's internal network, identified by the netname RAMKHAMHAENG and registrant IRT-RAMKHAMHAENG-TH.
  • The AS announces 8192 IPv4 addresses within a single prefix (202.41.160.0/19) and maintains 2 observed neighbours, a ratio consistent with an isolated institutional network rather than a transit or access provider.

Notable

  • The registrant IRT-RAMKHAMHAENG-TH and netname RAMKHAMHAENG align directly with the AS holder, Ramkhamhaeng University.
  • The address inventory consists of one contiguous /19 block, indicating a single, unified allocation for the institution's infrastructure.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
