AS8426: the CLARANET-AS ClaraNET LTD network

AS8426 is an internet Autonomous System operated by CLARANET-AS ClaraNET 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 AS8426?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8426 was assigned to CLARANET-AS ClaraNET LTD by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS8426 currently announces 80 IPv4 block(s), totaling about 904.2 thousand addresses (904,192 in all), registered in the United Kingdom. Services from CLARANET-AS ClaraNET LTD are reached through these addresses.

What it means to see AS8426 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8426. That means the other end sits on the CLARANET-AS ClaraNET LTD network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
