Summary
Prince of Songkla University (SritrangNET)
education university research legacy
AS9464 (PSU-TH-AS-AP) is held by Prince of Songkla University, Thailand's major public research university in the south of the country, with its main campus at Hat Yai and further campuses at Pattani, Phuket, Surat Thani and Trang. SritrangNET is the name of the university's own network.
What it's used for
RIS observes 9 IPv4 prefixes covering 3,840 addresses, 2 IPv6 prefixes (2001:c38:9718::/48 and 2001:3c8:9009::/48), and 5 BGP neighbours.
The reverse DNS confirms the holder directly: 192.100.77.5 resolves to ns.psu.ac.th, the university's own name server, sitting in a legacy 192.100.77.0/24. That is a positive identification, not an inference from the handle.
The five neighbours are more than a single-campus university usually needs, and the prefix mix explains why: alongside the university's core 202.29.144.0/22-area space there are blocks in 110.164.246.0/23 and 122.154.60.0/23, and the sampled PTRs on the 110.164.246.x addresses come back as static.3bb.co.th — reverse names belonging to 3BB, a Thai commercial broadband operator. That means part of this space is delegated commercial-provider address blocks the university announces itself, most plausibly for redundant links or for a distributed multi-campus footprint. It is a good illustration of the rule that rDNS shows what space carries, not who holds it: the 3BB names describe the address block's provenance, not the network's owner.
Notable
- The two IPv6
/48s come from separate Thai IPv6 allocations, one of them from the Thai research network's range, which is typical of a university connected to both academic and commercial upstreams. - Multiple campuses across southern Thailand explain the geographically split address blocks and the higher-than-expected neighbour count for a single institution.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
