AS213705: the SF-SERVICES network

AS213705 is an internet Autonomous System operated by SF-SERVICES (Moldova). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS213705?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS213705 was assigned to SF-SERVICES by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS213705 currently announces 41 IPv4 block(s), totaling about 36.6 thousand addresses (36,608 in all), registered in Moldova. Services from SF-SERVICES are reached through these addresses.

What it means to see AS213705 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS213705. That means the other end sits on the SF-SERVICES network (Moldova). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
