AS46103: the UWW-EDU-ASN network

AS46103 is an internet Autonomous System operated by UWW-EDU-ASN (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 AS46103?

Reach on the internet

AS46103 currently announces 3 IPv4 block(s), totaling about 65.5 thousand addresses (65,536 in all), registered in the United States. Services from UWW-EDU-ASN are reached through these addresses.

What it means to see AS46103 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS46103. That means the other end sits on the UWW-EDU-ASN network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
