What is AS19737?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS19737 was assigned to RMC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS19737 currently announces 1 IPv4 block(s), totaling about 65.5 thousand addresses (65,536 in all), registered in Canada. Services from RMC are reached through these addresses.
What it means to see AS19737 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS19737. That means the other end sits on the RMC network (Canada). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
