AS139570: the SPECTRUM-AS Spectrum Internet Services network

AS139570 is an internet Autonomous System operated by SPECTRUM-AS Spectrum Internet Services (India). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS139570?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS139570 was assigned to SPECTRUM-AS Spectrum Internet Services by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS139570 currently announces 2 IPv4 block(s), totaling about 1 thousand addresses (1,024 in all), registered in India. Services from SPECTRUM-AS Spectrum Internet Services are reached through these addresses.

What it means to see AS139570 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS139570. That means the other end sits on the SPECTRUM-AS Spectrum Internet Services network (India). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
