AS11293 — UCOP-ASN
Network type: education
AS11293 announces 16 IPv4 prefixes covering 53,772 addresses and 2 IPv6 prefixes.
About this network
UCOP-ASN belongs to the University of California Office of the President — the system-wide administrative headquarters of the ten-campus UC system, not any one campus. RIS sees 19 IPv4 prefixes, 53,760 addresses, no IPv6, and 3 observed neighbours.
What it's used for
UCOP's own administration and the system-wide services it runs on behalf of all the campuses: central IT, business and financial systems, and the shared library and digital-collection infrastructure the office has operated for decades. The sampled reverse DNS, by05-mgmt-01.ucop.edu, is a management host in the office's own .edu zone — first-party naming that ties the announced space directly to the holder rather than to an upstream or a customer.
Notable
Every prefix sampled is registered to the University of California - Office of the President, but the netnames are the interesting part: most of 128.48.0.0/16 is registered as UCDLA-NET-B and one of the 192.35.x /24s as UCDLA-FE1NET. UCDLA is an internal departmental code from UC's long-running library-automation and digital-library work, not a separate organisation. This is the classic case where the handle names nobody — read the org: field, which is UCOP throughout, and the apparent third-party registrant evaporates.
Interesting
Three observed neighbours against nearly 54,000 addresses is a research-and-education shape: a large institution that reaches the internet through a small number of upstreams (in the UC system's case, regional and national R&E networks) rather than peering broadly. Note also that this is an administrative network — classifying it as education is right because of what the organisation is and what the .edu space carries, but do not expect campus dormitory or student-residential traffic here. And the absence of announced IPv6 is a genuine gap for an institution of this size.
