education university usa

KSU-KENNESAW-01 is operated by Kennesaw State University.

What it's used for

  • The address space carries university infrastructure, with netnames KSC-1 and KSU-MARIETTA and registrants including Kennesaw State University and Southern Polytechnic State University.
  • The AS announces 69,632 IPv4 addresses across 2 prefixes with only 2 observed neighbours, a ratio indicating an isolated educational network rather than a transit provider.

Notable

  • Registrants align with the announcer, listing Kennesaw State University and Southern Polytechnic State University, reflecting the institution's history.
  • Southern Polytechnic State University merged with Kennesaw State University in 2013 to form the current institution, explaining the dual registrant history in the 168.28.176.0/20 block.
  • The inventory consists of two distinct IPv4 blocks: a /16 and a /20, with no IPv6 prefixes announced.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
