AS203380: the DAINTERNATIONALGROUP network

AS203380 is an internet Autonomous System operated by DAINTERNATIONALGROUP (Bulgaria). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS203380?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS203380 was assigned to DAINTERNATIONALGROUP by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS203380 currently announces 46 IPv4 block(s), totaling about 14.6 thousand addresses (14,592 in all), registered in Bulgaria. Services from DAINTERNATIONALGROUP are reached through these addresses.

What it means to see AS203380 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS203380. That means the other end sits on the DAINTERNATIONALGROUP network (Bulgaria). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
