Summary

Universitas Sanata Dharma

Indonesia · AI-generated

education university catholic indonesia

USD-AS-ID is operated by Universitas Sanata Dharma.

What it's used for

  • The address space carries university infrastructure, evidenced by reverse DNS entries such as infra.usd.ac.id and e-journal.usd.ac.id.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained institutional network rather than a transit or large-scale access provider.
  • Traffic consists of internal university services, including academic resources and administrative systems for the institution's staff and students.

Notable

  • Registrants for both announced prefixes are listed as Universitas Sanata Dharma, matching the AS holder.
  • The address inventory is compact, consisting of two /24 blocks, which is typical for a single-site academic institution.

Reputation

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
