AS3233: the ICI-ROTLD Romanian National R&D Network network

AS3233 is an internet Autonomous System operated by ICI-ROTLD Romanian National R&D Network (Romania). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS3233?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS3233 was assigned to ICI-ROTLD Romanian National R&D Network by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS3233 currently announces 27 IPv4 block(s), totaling about 105.2 thousand addresses (105,216 in all), registered in Romania. Services from ICI-ROTLD Romanian National R&D Network are reached through these addresses.

What it means to see AS3233 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS3233. That means the other end sits on the ICI-ROTLD Romanian National R&D Network network (Romania). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
