Summary

Youngstown State University

United States of America · AI-generated

education university ohio public

The AS handle YSU-AS is held by Youngstown State University.

What it's used for

  • The address space carries university infrastructure, evidenced by the reverse DNS record 0804ar2.kc.ysu.edu and the netname YSU1.
  • The network announces 65536 IPv4 addresses within a single /16 prefix (150.134.0.0/16) and maintains only 1 observed neighbour, a ratio typical of an access or internal campus network rather than a transit provider.

Notable

  • The RDAP registrant Youngstown State University aligns perfectly with the AS holder name, confirming direct ownership of the address space.
  • Youngstown State University is a public institution in Youngstown, Ohio, and the easternmost member of the University System of Ohio.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a standard on-campus allocation.

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 1,779 prefixes, as published 2026-10-21. 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.
