AS5482: the AS5482 Allpoints Fibre Networks Ltd network

AS5482 is an internet Autonomous System operated by AS5482 Allpoints Fibre Networks 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 AS5482?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS5482 was assigned to AS5482 Allpoints Fibre Networks Ltd by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS5482 currently announces 5 IPv4 block(s), totaling about 44 thousand addresses (44,032 in all), registered in the United Kingdom. Services from AS5482 Allpoints Fibre Networks Ltd are reached through these addresses.

What it means to see AS5482 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS5482. That means the other end sits on the AS5482 Allpoints Fibre Networks Ltd network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
