AS9431: the AKUNI-NZ The University of Auckland network

AS9431 is an internet Autonomous System operated by AKUNI-NZ The University of Auckland (New Zealand). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS9431?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9431 was assigned to AKUNI-NZ The University of Auckland by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS9431 currently announces 3 IPv4 block(s), totaling about 66 thousand addresses (66,048 in all), registered in New Zealand. Services from AKUNI-NZ The University of Auckland are reached through these addresses.

What it means to see AS9431 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9431. That means the other end sits on the AKUNI-NZ The University of Auckland network (New Zealand). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
