Summary

University of Santo Tomas

Philippines · AI-generated

education business university

The AS handle UST-AS-AP is held by University of Santo Tomas.

What it's used for

  • The address space carries the University of Santo Tomas, as indicated by the netname UST and registrants including University of Santo Tomas - Network Operations Center and University of Santo Tomas - Hostmaster.
  • The AS announces 4096 IPv4 addresses across 1 prefix (202.65.176.0/20) and maintains 2 observed neighbours, a ratio consistent with an internal corporate or institutional estate rather than a transit provider.

Notable

  • The RDAP registrants align directly with the announcer, listing University of Santo Tomas and its network operations team.
  • The inventory consists of a single contiguous /20 block, reflecting a finely subdivided internal network structure typical of a large campus or corporate entity.

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 1,852 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.
