AS5563: the URAL Ural Regional Net network

AS5563 is an internet Autonomous System operated by URAL Ural Regional Net (Russia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS5563?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS5563 was assigned to URAL Ural Regional Net by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS5563 currently announces 19 IPv4 block(s), totaling about 64 thousand addresses (64,000 in all), registered in Russia. Services from URAL Ural Regional Net are reached through these addresses.

What it means to see AS5563 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS5563. That means the other end sits on the URAL Ural Regional Net network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
