AS47625: the UKHOST4U network

AS47625 is an internet Autonomous System operated by UKHOST4U (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 AS47625?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS47625 was assigned to UKHOST4U by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS47625 currently announces 3 IPv4 block(s), totaling about 3.1 thousand addresses (3,072 in all), registered in the United Kingdom. Services from UKHOST4U are reached through these addresses.

What it means to see AS47625 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS47625. That means the other end sits on the UKHOST4U network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
