AS9472 PSL-AU Level 23, Exchange Plaza

AS9472 carries the as-name PSL-AU and a registry description that is just a street address — Level 23, Exchange Plaza — the Perth tower (now Exchange Tower, at 2 The Esplanade) where the holder's head office sat. WHOIS-derived sources now report the organisation behind the AS as Canaccord Genuity Financial Limited, which is what Patersons Securities Limited was renamed after Canaccord Genuity completed its acquisition of the Perth stockbroking and wealth-management firm in October 2019. PSL is Patersons Securities Limited; the handle is a fossil of the pre-acquisition name.

What it's used for

RIS observes 3 IPv4 prefixes covering 768 addresses — three consecutive /24s, 103.4.160.0/24 through 103.4.162.0/24 — and 1 BGP neighbour. No IPv6 is announced.

This is a corporate end site. A single upstream and three contiguous /24s out of one APNIC allocation is what a financial-services firm looks like when it wants portable address space for its own perimeter — client-facing trading and advisory platforms, mail, remote access for advisers across its Australian offices — but has no need to be a network operator. There is no eyeball scale, no customer sub-allocation, no wholesale peering, and no hosting fan-out.

The single neighbour is worth noting against the pattern seen at other brokerages, which typically multihome aggressively; this network takes one transit path.

Notable

• Patersons was founded in Perth in 1903 as an accounting practice and moved into stockbroking in the 1920s, growing into a national wealth manager before the Canaccord deal.
• This is a name-collision trap in miniature: neither PSL-AU nor "Level 23, Exchange Plaza" identifies anything on its own. The AS is only legible once the registry's organisation field is followed through to Canaccord Genuity.
