AS36712: the CONTIN-83-1 network

AS36712 is an internet Autonomous System operated by CONTIN-83-1 (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 AS36712?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS36712 was assigned to CONTIN-83-1 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS36712 currently announces 23 IPv4 block(s), totaling about 68.9 thousand addresses (68,864 in all), registered in the United States. Services from CONTIN-83-1 are reached through these addresses.

What it means to see AS36712 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS36712. That means the other end sits on the CONTIN-83-1 network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
