AS12491: the GILAT-TELECOM-LTD network

AS12491 is an internet Autonomous System operated by GILAT-TELECOM-LTD (Israel). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS12491?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12491 was assigned to GILAT-TELECOM-LTD by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS12491 currently announces 54 IPv4 block(s), totaling about 45.1 thousand addresses (45,056 in all), registered in Israel. Services from GILAT-TELECOM-LTD are reached through these addresses.

What it means to see AS12491 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12491. That means the other end sits on the GILAT-TELECOM-LTD network (Israel). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
