What is AS211001?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS211001 was assigned to TTR-GROUP by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS211001 currently announces 3 IPv4 block(s), totaling 768 addresses (768 in all), registered in Hong Kong. Services from TTR-GROUP are reached through these addresses.
What it means to see AS211001 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS211001. That means the other end sits on the TTR-GROUP network (Hong Kong). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
