Summary
Ontario Institute for Cancer Research
research education legacy
OICR-ONTARIO-INSTITUTE-FOR-CANCER-RESEARCHB belongs to the Ontario Institute for Cancer Research, the provincially funded not-for-profit cancer research institute based at the MaRS Discovery District in Toronto. RIS sees 2 IPv4 prefixes, about 2,304 addresses, no IPv6, and 2 observed BGP neighbours.
What it's used for
Research-institute connectivity: laboratory and office networking, and the genomics and computational-biology workloads that dominate a modern cancer institute — sequencing pipelines, large data archives, and the collaborative data-sharing that comes with international consortium work. The shape of the inventory says end-site, not carrier. A /21 registered directly to OICR under the OICRNET handle is the institute's own space; the second prefix, 159.18.95.0/24, registers to Zayo Bandwidth, which is provider-assigned space announced by the customer rather than a third-party registrant of the kind that would signal leased or brokered addresses. Two BGP neighbours against roughly two thousand addresses is exactly what a research end-site with a couple of upstreams looks like: it buys transit, it does not sell it.
Notable
The address count is small for a research institute, and that is the point. OICR's heavy lifting is not done on public IPv4 — institutions of this kind run their science on private RFC 1918 space behind a small public edge, and reach national research infrastructure over dedicated research-network paths rather than through the commodity internet. Two prefixes and two neighbours describe the front door, not the building.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-20. 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.
