AS45570: the NETPRES-AS-AP Network Presence network

AS45570 is an internet Autonomous System operated by NETPRES-AS-AP Network Presence (Australia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS45570?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS45570 was assigned to NETPRES-AS-AP Network Presence by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS45570 currently announces 6 IPv4 block(s), totaling about 3.1 thousand addresses (3,072 in all), registered in Australia. Services from NETPRES-AS-AP Network Presence are reached through these addresses.

What it means to see AS45570 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS45570. That means the other end sits on the NETPRES-AS-AP Network Presence network (Australia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
