About this network

AS9880 (NEXTGENNET-AS1-AU-AP) is held by NextGen.Net Pty Ltd of North Sydney, an Australian technology company that builds lending software for the mortgage industry. Its ApplyOnline platform is used by Australian mortgage brokers and lenders to lodge and process home-loan applications electronically. Despite the .Net in the name, this is not an internet service provider.

What it's used for

The routing evidence describes a private corporate network, not a service provider. RIS sees 9 IPv4 prefixes carrying 57,856 addresses, no IPv6, and only 1 observed BGP neighbour. A single neighbour is decisive: the AS buys connectivity from one upstream and sells transit to nobody. The address count comes almost entirely from seven /19s carved out of the legacy 164.80.0.0/16 block, announced as separate pieces rather than as one aggregate, plus two small /24s in 203.33.x. That is a company with a large historical allocation running a platform behind it, not a network with 57,000 users.

Notable

• The name is a trap worth calling out. NextGen.Net reads like a dial-up-era ISP handle, and the AS is in the low-9000s where ISPs cluster, but the organisation is a financial-technology vendor. This is exactly the case where reading the business off the handle produces a wrong answer.
• Because the platform sits between brokers, aggregators and lenders, traffic to and from this AS is business-to-business application traffic — lodgement, document exchange, credit and open-banking integrations — rather than consumer eyeball traffic.
• The 164.80.0.0/16 space is a legacy allocation; announcing it as seven /19s rather than one /16 is a deliberate routing choice, not a sign of fragmentation across owners.
