AS36454: the WHG-DAL network

AS36454 is an internet Autonomous System operated by WHG-DAL (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 AS36454?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS36454 was assigned to WHG-DAL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS36454 currently announces 21 IPv4 block(s), totaling about 14.1 thousand addresses (14,080 in all), registered in the United Kingdom. Services from WHG-DAL are reached through these addresses.

What it means to see AS36454 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS36454. That means the other end sits on the WHG-DAL network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
