Summary

University of the Philippines Diliman

Philippines · AI-generated

education university academic

DILNET-AS-AP is operated by University of the Philippines Diliman.

What it's used for

  • The address space carries academic infrastructure, evidenced by reverse DNS records pointing to upd.edu.ph and netnames like DilNet, UP-NET, and DilNet-CSRC.
  • The AS announces 3072 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, with 7 observed neighbours, indicating a self-contained institutional network rather than a transit provider.

Notable

  • Registrants consistently identify as IRT-UP-PH, UPCC TECH, and University of the Philippines, aligning perfectly with the announcer.
  • The inventory is finely subdivided into specific functional blocks such as DilNet-P2P and DilNet-CC, reflecting internal site-by-site segmentation typical of a large university campus.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
