AS8622: the ISIONUK Team Blue Internet Services UK Ltd network

AS8622 is an internet Autonomous System operated by ISIONUK Team Blue Internet Services UK Ltd (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 AS8622?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8622 was assigned to ISIONUK Team Blue Internet Services UK Ltd by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS8622 currently announces 5 IPv4 block(s), totaling about 41.2 thousand addresses (41,216 in all), registered in the United Kingdom. Services from ISIONUK Team Blue Internet Services UK Ltd are reached through these addresses.

What it means to see AS8622 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8622. That means the other end sits on the ISIONUK Team Blue Internet Services UK Ltd network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
