AS4770: the ICONZ-AS ICONZ Ltd network

AS4770 is an internet Autonomous System operated by ICONZ-AS ICONZ Ltd (New Zealand). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS4770?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS4770 was assigned to ICONZ-AS ICONZ Ltd by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS4770 currently announces 12 IPv4 block(s), totaling about 63 thousand addresses (62,976 in all), registered in New Zealand. Services from ICONZ-AS ICONZ Ltd are reached through these addresses.

What it means to see AS4770 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS4770. That means the other end sits on the ICONZ-AS ICONZ Ltd network (New Zealand). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
