AS11105 SFU-AS

SFU-AS is Simon Fraser University, the public research university in Burnaby, British Columbia. Every announced prefix is registered to an SFU handle (SFU-CA, SFU-207-23-192, NETBLK-SFUCSS, NET-SFU-EXT and others), and the reverse DNS is first-party throughout — sfu.ca. This is a campus network holding and using its own space.

What it's used for

Campus connectivity and research computing. The AS announces 19 IPv4 prefixes (~94,720 addresses), anchored on a legacy 142.58.0.0/16, plus IPv6 out of 2607:f8f0:690::/48. RIS observes only 1 neighbour, which is normal for a Canadian university: campuses connect through their provincial research network (BCNET in British Columbia) rather than buying commercial transit directly, so the whole institution reaches the internet through a single upstream relationship.

Notable

The reverse DNS reads like a campus floor plan. p207-023-192-005.wireless.sfu.ca and p207-023-160-005.wireless.sfu.ca are the campus Wi-Fi pools — two whole /19s of them, which is where most of the address count goes. border-p5.nat.sfu.ca is a NAT border host, ns-wtb-mine.its.sfu.ca sits with IT Services, and rcg-deploy2.dcr.sfu.ca belongs to research computing.

Interesting

206.12.120.0/21 answers as cloud.computecanada.ca — national research-computing infrastructure, part of Canada's shared advanced-research computing estate, hosted inside SFU's address space. A university AS is rarely just students and staff: it routinely carries national-scale research systems that happen to be physically sited on that campus, which is why address count is a poor proxy for enrolment and why "education" here covers workloads that look nothing like a lecture theatre.
