What is AS1100?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS1100 was assigned to NUDAY by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS1100 currently announces 19 IPv4 block(s), totaling about 10.5 thousand addresses (10,496 in all), registered in Canada. Services from NUDAY are reached through these addresses.
What it means to see AS1100 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS1100. That means the other end sits on the NUDAY 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.
