AS49765: the COMMS365 network

AS49765 is an internet Autonomous System operated by COMMS365 (the United Kingdom). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS49765?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS49765 was assigned to COMMS365 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS49765 currently announces 10 IPv4 block(s), totaling about 21.5 thousand addresses (21,504 in all), registered in the United Kingdom. Services from COMMS365 are reached through these addresses.

What it means to see AS49765 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS49765. That means the other end sits on the COMMS365 network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
