AS12946: the TELECABLE Spain network

AS12946 is an internet Autonomous System operated by TELECABLE Spain (Spain). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS12946?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12946 was assigned to TELECABLE Spain by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS12946 currently announces 13 IPv4 block(s), totaling about 223.7 thousand addresses (223,744 in all), registered in Spain. Services from TELECABLE Spain are reached through these addresses.

What it means to see AS12946 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12946. That means the other end sits on the TELECABLE Spain network (Spain). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
