AS7377 — University of California, San Diego

University of California, San Diego (AS7377) is a consumer and business internet provider. The 166 addresses we have observed on it are the kind an ISP assigns to homes, offices and mobile devices — connections with a person behind them, not rented servers.

None of those 166 addresses carried a threat flag or a notable risk score when last checked. That is the profile you would expect from an ordinary access network: its addresses turn up in logs because people use the internet, not because infrastructure lives here.

Addresses on this network have been looked up through Predax between February 10, 2026 and February 12, 2026. Each figure on this page reflects an address's most recent check, not a permanent record.

Geographically, the observed addresses span 17 countries, with the largest share (128 of 166) geolocating to United States.

Traffic from this network is your audience, not your threat surface. Blocking an access network at this level turns away real people, and nothing in our observations justifies it.

If an individual address from this network is causing problems — failed logins, scraping, card testing — act on that address and that behaviour. Its report page shows what we know; the network-level numbers here are the context, not the verdict.
