Testar grátis 14 dias →AS2543 is an internet Autonomous System operated by UCIMC-AS (the United States). Here is what that means and why this number may show up when you investigate a connection on your network.
What is AS2543?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS2543 was assigned to UCIMC-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS2543 currently announces 1 IPv4 block(s), totaling 4 addresses (4 in all), registered in the United States. Services from UCIMC-AS are reached through these addresses.
What it means to see AS2543 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS2543. That means the other end sits on the UCIMC-AS network (the United States). 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
