AS25003: the INTERNET_BINAT Internet Binat network

AS25003 is an internet Autonomous System operated by INTERNET_BINAT Internet Binat (Israel). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS25003?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS25003 was assigned to INTERNET_BINAT Internet Binat by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS25003 currently announces 42 IPv4 block(s), totaling about 31 thousand addresses (30,976 in all), registered in Israel. Services from INTERNET_BINAT Internet Binat are reached through these addresses.

What it means to see AS25003 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS25003. That means the other end sits on the INTERNET_BINAT Internet Binat network (Israel). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
