What is AS7311?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS7311 was assigned to FRONTIER by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS7311 currently announces 33 IPv4 block(s), totaling about 126 thousand addresses (125,952 in all), registered in Canada. Services from FRONTIER are reached through these addresses.
What it means to see AS7311 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS7311. That means the other end sits on the FRONTIER network (Canada). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
How to see every connection and network your devices reach
Tracing one connection's ASN at a time is tedious. Sentinela, by PC Monitor, maps the devices on your network, shows what is exposed to the internet and helps flag suspicious connections and devices — running on your Windows. Meet Sentinela.
