AS8674: the NETNOD-IX Netnod AB network

AS8674 is an internet Autonomous System operated by NETNOD-IX Netnod AB (Sweden). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS8674?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8674 was assigned to NETNOD-IX Netnod AB by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS8674 currently announces 10 IPv4 block(s), totaling about 7.9 thousand addresses (7,936 in all), registered in Sweden. Services from NETNOD-IX Netnod AB are reached through these addresses.

What it means to see AS8674 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8674. That means the other end sits on the NETNOD-IX Netnod AB network (Sweden). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
