AS4788: the TTSSB-MY TM TECHNOLOGY SERVICES SDN. BHD. network

AS4788 is an internet Autonomous System operated by TTSSB-MY TM TECHNOLOGY SERVICES SDN. BHD. (Malaysia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS4788?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS4788 was assigned to TTSSB-MY TM TECHNOLOGY SERVICES SDN. BHD. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS4788 currently announces 64 IPv4 block(s), totaling about 3.2 million addresses (3,248,384 in all), registered in Malaysia. Services from TTSSB-MY TM TECHNOLOGY SERVICES SDN. BHD. are reached through these addresses.

What it means to see AS4788 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS4788. That means the other end sits on the TTSSB-MY TM TECHNOLOGY SERVICES SDN. BHD. network (Malaysia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
