AS11918: the DIALLOGTORONTOCORE network

AS11918 is an internet Autonomous System operated by DIALLOGTORONTOCORE (Canada). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS11918?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS11918 was assigned to DIALLOGTORONTOCORE by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS11918 currently announces 4 IPv4 block(s), totaling about 3.1 thousand addresses (3,072 in all), registered in Canada. Services from DIALLOGTORONTOCORE are reached through these addresses.

What it means to see AS11918 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS11918. That means the other end sits on the DIALLOGTORONTOCORE network (Canada). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
