About this network

AS9798 (BLACKBERRY-SG) is registered to BlackBerry Singapore Pte. Limited. The holder string in the registry is not a company name at all but the company's street address, 1 International Business Park in Singapore's Jurong East business park, which is why lookups against the raw registry data often show something that reads like a property rather than an operator.

What it's used for

A corporate network, and a small one. RIS sees exactly 1 IPv4 prefix, 111.221.8.0/21, carrying 2,048 addresses, with a single observed BGP neighbour and no IPv6. One prefix and one adjacency is a network with no ambition to be reachable by many paths: it is a block of addresses attached to a company's own infrastructure through one provider. BlackBerry's Asia-Pacific presence historically included operational infrastructure for its messaging and enterprise-device services, and a regionally allocated /21 announced from a company-held ASN is consistent with that kind of back-end estate rather than with anything customer-facing or resold. There is nothing in the routing to suggest hosting, transit or eyeball activity.

Notable

• The company behind the AS is the Canadian firm now focused on enterprise security and embedded software rather than the handset business the name is remembered for; this is its Singapore entity.
• Some routing databases have at times shown this ASN as not visible in the global table, so its announcement has evidently not been continuous over the years.
• A /21 is a large-ish enterprise allocation by APNIC standards, considerably more than a normal corporate office would need.
