AS49071: the SWISSTXT Schweizerische Teletext AG network

AS49071 is an internet Autonomous System operated by SWISSTXT Schweizerische Teletext AG (Switzerland). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS49071?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS49071 was assigned to SWISSTXT Schweizerische Teletext AG by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS49071 currently announces 4 IPv4 block(s), totaling about 67.8 thousand addresses (67,840 in all), registered in Switzerland. Services from SWISSTXT Schweizerische Teletext AG are reached through these addresses.

What it means to see AS49071 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS49071. That means the other end sits on the SWISSTXT Schweizerische Teletext AG network (Switzerland). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
