What is AS37518?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS37518 was assigned to FIBERGRID by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS37518 currently announces 220 IPv4 block(s), totaling about 937.7 thousand addresses (937,728 in all), registered in SC. Services from FIBERGRID are reached through these addresses.
What it means to see AS37518 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS37518. That means the other end sits on the FIBERGRID network (SC). 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.
