What is AS19102?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS19102 was assigned to PCI-TW by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS19102 currently announces 2 IPv4 block(s), totaling 512 addresses (512 in all), registered in the United States. Services from PCI-TW are reached through these addresses.
What it means to see AS19102 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS19102. That means the other end sits on the PCI-TW network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
