AS4983: the INTEL-SC-AS network

AS4983 is an internet Autonomous System operated by INTEL-SC-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 AS4983?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS4983 was assigned to INTEL-SC-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS4983 currently announces 40 IPv4 block(s), totaling about 38.9 thousand addresses (38,912 in all), registered in the United States. Services from INTEL-SC-AS are reached through these addresses.

What it means to see AS4983 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS4983. That means the other end sits on the INTEL-SC-AS network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
