AS9468 IBLLC-HK INTERACTIVE BROKERS LLC

AS9468 (IBLLC-HK) is held by Interactive Brokers, the electronic brokerage and market-maker, for its Hong Kong operation. The handle spells it out: IBLLC is Interactive Brokers LLC, and the -HK suffix marks this as the Asia-Pacific-registered network rather than the firm's US space. It is a financial enterprise announcing its own address space, not a service provider.

What it's used for

RIS observes 4 IPv4 prefixes covering 768 addresses and 3 BGP neighbours. No IPv6 is announced. The prefixes are 103.38.90.0/23 — announced both as the /23 and as its two constituent /24s — plus a separate legacy 202.1.6.0/24.

Three upstreams on 768 addresses is the signature of a network where reachability matters far more than capacity. That is exactly right for a brokerage: the addresses front trading gateways, client API endpoints and market-data connectivity for the Asian trading day, and an outage on one transit provider during market hours is unacceptable. Announcing both the covering /23 and its component /24s is a standard traffic-engineering move — it lets the firm steer inbound traffic per-/24 across its upstreams while keeping the aggregate as a fallback, and it gives some protection against more-specific hijacks.

There is nothing here that carries anyone else's traffic. No customer allocations, no wholesale peering, no hosting scale. Fewer than a thousand addresses, heavily multihomed, is a self-contained corporate edge.

Notable

• The mix of a modern 103.x APNIC /22-neighbourhood block with an old 202.1.6.0/24 suggests space acquired in two eras, which is common for financial firms that established an Asian presence early and expanded later.
• Deliberate deaggregation of the /23 into /24s is a common pattern among latency- and availability-sensitive financial networks.
