Summary

University of San Francisco

United States of America · AI-generated

education university usf san-francisco

The AS handle USFCA is operated by University of San Francisco.

What it's used for

  • The address space carries the institutional network for the University of San Francisco, with all registrant netnames set to USFCA and registrants listed as University of San Francisco.
  • The AS announces 65,536 IPv4 addresses across 14 prefixes, all within the 138.202.0.0/16 range, and maintains 3 observed neighbours, a ratio consistent with a single-site institutional network rather than a transit or access provider.

Notable

  • All 12 sampled RDAP registrants agree with the announcer, uniformly listing University of San Francisco as the registrant and USFCA as the netname.
  • The address inventory is a contiguous block of 14 prefixes spanning /17 through /24 sizes, all within 138.202.0.0/16, indicating a single, finely subdivided corporate 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 1,779 prefixes, as published 2026-10-22. 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.
