AS4618: the INET-TH-AS Internet Thailand Company Limited network

AS4618 is an internet Autonomous System operated by INET-TH-AS Internet Thailand Company Limited (Thailand). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS4618?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS4618 was assigned to INET-TH-AS Internet Thailand Company Limited by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS4618 currently announces 123 IPv4 block(s), totaling about 218.6 thousand addresses (218,624 in all), registered in Thailand. Services from INET-TH-AS Internet Thailand Company Limited are reached through these addresses.

What it means to see AS4618 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS4618. That means the other end sits on the INET-TH-AS Internet Thailand Company Limited network (Thailand). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
