Summary

university education research legacy

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
