Summary

University of Dayton

United States of America · AI-generated

education university research ohio

The AS handle UD-ACA-AS is held by University of Dayton.

What it's used for

  • The address space carries the university's internal network, with all registrant netnames set to DAYTON and registrants listed as University of Dayton.
  • The AS announces 65,280 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes agree with the announcer, consistently identifying University of Dayton as the holder.
  • The address inventory is finely subdivided into ten distinct IPv4 prefixes within the 131.238.0.0/16 range, reflecting site-by-site segmentation typical of a large institutional estate.

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 1,778 prefixes, as published 2026-10-20. 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.
