AS9749 GPKNET-AS-AU GPK Group

AS9749 (GPKNET-AS-AU) is held by GPK Group Pty Ltd, an Australian managed IT services provider based in Hallam, Victoria. GPK sells managed IT, networking, hardware and support to business customers — notably in the retail sector — rather than selling internet access to the public.

What it's used for

The AS is the connectivity layer under GPK's managed services. RIS shows 13 IPv4 prefixes covering 5,376 addresses, plus two IPv6 announcements (2001:df0:c2::/48 and 2401:5500::/32), and only 3 observed BGP neighbours. The v4 space is dominated by a 119.224.144.0/20 aggregate, which the AS then deaggregates into a run of /24s inside that same block, with a 203.62.220.0/22 and a lone 203.23.142.0/24 alongside it. Announcing a /20 together with most of its component /24s is the fingerprint of a provider that assigns small blocks to individual customer sites and wants each one steerable in its own right. Three BGP neighbours confirms the role: this network buys transit from a couple of upstreams and terminates traffic with its own customers. It carries nobody else's routes.

Notable

• The 119.224.0.0/16 range this AS draws from is more commonly seen in New Zealand allocations, but the sub-block here is registered to GPK's Australian network. The prefix range is not a reliable country signal.
• A managed-services AS of this size is best understood as many small business networks stitched behind one origin, not as a single corporate site.
• The IPv6 posture is ahead of the IPv4 one: a full /32 for a network with only about five thousand IPv4 addresses.
