AS12775: the JPCINET The JPCINET Autonomous System network

AS12775 is an internet Autonomous System operated by JPCINET The JPCINET Autonomous System (the United Kingdom). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS12775?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12775 was assigned to JPCINET The JPCINET Autonomous System by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS12775 currently announces 3 IPv4 block(s), totaling about 8.7 thousand addresses (8,704 in all), registered in the United Kingdom. Services from JPCINET The JPCINET Autonomous System are reached through these addresses.

What it means to see AS12775 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12775. That means the other end sits on the JPCINET The JPCINET Autonomous System network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
