AS11489 BACI

BACI is registered to Bell Canada (ARIN records the ASN from 1998, Ottawa), but what it actually carries is the Government of Quebec. RIS sees 39 IPv4 prefixes and roughly 308,000 addresses — a large inventory — against only 2 observed BGP neighbours and no IPv6 at all.

What it's used for

Managed network services for Quebec public bodies. Read the prefix registrants and the picture is unambiguous: 132.221.0.0/16 is registered to the Ministère des Transports du Québec, 142.213.0.0/16 to the Gouvernement du Québec, and a whole family of blocks — 142.83.0.0/16, 142.84.128.0/17, 142.85.0.0/17, 142.83.192.0/18 and more — to Santé Québec, the province's health agency. Bell is the carrier; the address space belongs to its customer. This is the textbook carrier-announces-customer-PI-space pattern, and the registrants here are not unrelated third parties but a single provincial government's departments, which is why it should not be read as leased or brokered address space.

Notable

The routing shape is worth pausing on. Three hundred thousand addresses would suggest a substantial ISP, yet only two neighbours are observed — a wholesale carrier peers with hundreds. That combination says a single-purpose AS: one big customer relationship, homed into Bell, aggregating a province's ministries and hospitals rather than selling transit. Geolocation of this space should follow Quebec, not Bell's Ottawa registration address.
