Summary

King Saud University

Saudi Arabia · AI-generated

education university saudi-arabia

KSU is the autonomous system for King Saud University.

What it's used for

  • The address space carries university infrastructure, identified by netnames such as SA-KING-SAUD-UNIVERSITY-20100112 and KSU-Internet_Module_ISP_KACST.
  • The AS announces 8,192 IPv4 addresses across 6 prefixes with 2 observed neighbours, a ratio consistent with an internal campus network rather than a transit provider.
  • Traffic from this AS consists of academic and administrative endpoints for the university's staff, students, and research facilities in Riyadh.

Notable

  • Registrants for the majority of prefixes are listed as King Saud University, aligning with the AS holder.
  • The address inventory is finely subdivided into six distinct IPv4 prefixes, reflecting site-by-site segmentation within the university estate.
  • Two smaller prefixes use different netnames (KSU-Internet_Module_ISP_KACST and KSU_Planned_ISP3-Internet) but remain under the same registrant umbrella.

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 1,773 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.

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.
