What is AS12217?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12217 was assigned to UPS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS12217 currently announces 17 IPv4 block(s), totaling about 75 thousand addresses (75,008 in all), registered in the United States. Services from UPS are reached through these addresses.
What it means to see AS12217 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12217. That means the other end sits on the UPS network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
