Unclassified APNIC
Summary
BlackBerry Singapore
enterprise legacy
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
/21is a large-ish enterprise allocation by APNIC standards, considerably more than a normal corporate office would need.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,782 prefixes, as published 2026-10-16. 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.
